7 Detailed Description

7.1 Overview

The DCP01B offers up to 1 W of isolated, unregulated output power from a 5-V, 15-V, or 24-V input source with a typical efficiency of up to 85%. This efficiency is achieved through highly integrated packaging technology and the implementation of a custom power stage and control device. The DCP01B devices are specified for operational isolation only. The circuit design uses an advanced BiCMOS and DMOS process.

7.3 Feature Description

7.3.1 Isolation

Underwriters Laboratories, UL™ defines several classes of isolation that are used in modern power supplies. Safety extra low voltage (SELV) is defined by UL (UL1950 E199929) as a secondary circuit which is so designated and protected that under normal and single fault conditions the voltage between any two accessible parts, or between an accessible part and the equipment earthing terminal for operational isolation does not exceed steady state 42.5 V peak or 60 VDC for more than one second.

7.3.1.1 Operation or Functional Isolation

Operational or functional isolation is defined by the use of a high-potential (hipot) test only. Typically, this isolation is defined as the use of insulated wire in the construction of the transformer as the primary isolation barrier. The hipot one-second duration test (dielectric voltage, withstand test) is a production test used to verify that the isolation barrier is functioning. Products with operational isolation must never be used as an element in a safety-isolation system.

7.3.1.2 Basic or Enhanced Isolation

Basic or enhanced isolation is defined by specified creepage and clearance limits between the primary and secondary circuits of the power supply. Basic isolation is the use of an isolation barrier in addition to the insulated wire in the construction of the transformer. Input and output circuits must also be physically separated by specified distances.

7.3.1.3 Continuous Voltage

For a device that has no specific safety agency approvals (operational isolation), the continuous voltage that can be applied across the part in normal operation is less than 42.5 VRMS, or 60 VDC. Ensure that both input and output voltages maintain normal SELV limits. The isolation test voltage represents a measure of immunity to transient voltages. WARNING Do not use the device as an element of a safety isolation system that exceeds the SELV limit. If the device is expected to function correctly with more than 42.5 VRMS or 60 VDC applied continuously across the isolation barrier, then the circuitry on both sides of the barrier must be regarded as operating at an unsafe voltage, and further isolation or insulation systems must form a barrier between these circuits and any user- accessible circuitry according to safety standard requirements.

7.3.1.4 Isolation Voltage

The terms Hipot test, flash-tested, withstand voltage, proof voltage, dielectric withstand voltage, and isolation test voltage all describe a similar idea. They describe a test voltage applied for a specified time across a component designed to provide electrical isolation to verify the integrity of that isolation. TI’s DCP01B series of DC/DC converters are all 100% production tested at 1.0 kVAC for one second.

7.3.1.5 Repeated High-Voltage Isolation Testing

Repeated high-voltage isolation testing of a barrier component can degrade the isolation capability, depending on materials, construction, and environment. The DCP01B series of DC/DC converters have toroidal, enameled, wire isolation transformers with no additional insulation between the primary and secondary windings. While a device can be expected to withstand several times the stated test voltage, the isolation capability depends on the wire insulation. Any material, including this enamel (typically polyurethane), is susceptible to eventual chemical degradation when subject to very-high applied voltages. Therefore, strictly limit the number of high- voltage tests and repeated high-voltage isolation testing. However, if it is absolutely required, reduce the voltage by 20% from specified test voltage with a duration limit of one second per test. www.ti.com DCP010505B, DCP010512B, DCP010515B, DCP012405B, DCP010505DB, DCP010507DB, DCP010512DB, DCP010515DB, DCP011512DB, DCP011515DB, DCP012415DB SBVS012I – DECEMBER 2000 – REVISED SEPTEMBER 2020 Copyright © 2020 Texas Instruments Incorporated Submit Document Feedback 13 Product Folder Links: DCP010505B DCP010512B DCP010515B DCP012405B DCP010505DB DCP010507DB DCP010512DB DCP010515DB DCP011512DB DCP011515DB DCP012415DB

7.3.2 Power Stage

The DCP01B series of devices uses a push-pull, center-tapped topology. The DCP01B devices switch at 400 kHz (divide-by-2 from an 800-kHz oscillator).

7.3.3 Oscillator And Watchdog Circuit

The onboard, 800-kHz oscillator generates the switching frequency by a divide-by-2 circuit. The oscillator can be synchronized to other DCP01B series device circuits or an external source, and is used to minimize system noise. A watchdog circuit checks the operation of the oscillator circuit. The oscillator can be disabled by pulling the SYNCIN pin low. When the SYNCIN pin goes low, the output pins transition into tri-state mode, which occurs within 2 μs.

7.3.4 Thermal Shutdown

The DCP01B series of devices are protected by a thermal-shutdown circuit. If the on-chip temperature rises above 150°C, the device shuts down. Normal operation resumes as soon as the temperature falls below 150°C. While the over temperature condition continues, operation randomly cycles on and off. This cycling continues until the temperature is reduced.

7.3.5 Synchronization

When more than one DC/DC converter is needed onboard, beat frequencies and other electrical interference can be generated. This interference occurs because of the small variations in switching frequencies between the DC/DC converters. The DCP01B series of devices overcomes this interference by allowing devices to synchronize to one another. Synchronize up to eight devices by connecting the SYNC pins of each device, taking care to minimize the capacitance of tracking. Stray capacitance (greater than 3 pF) reduces the switching frequency, or can sometimes stop the oscillator circuit. The maximum recommended voltage applied to the SYNC pin is 3.0 V. For an application that uses more than eight synchronized devices, use an external device to drive the SYNC pins. The application report External Synchronization of the DCP01/02 Series of DC/DC Converters describes this configuration. Note During the start-up period, all synchronized devices draw maximum current from the input simultaneously. If the input voltage falls below approximately 4 V, the devices may not start up. A 2.2-μF capacitor should be connected close to each device input pin.

7.3.6 Light Load Operation (< 10%)

Operation below 10% load can cause the output voltage to increase up to double the typical output voltage. For applications that operate less than 10% of rated output current, it is recommended to add a minimum load to ensure the output voltage of the device is within the load regulation range. For example, connect a 250-Ω pre- load resistor to meet the 10% minimum load condition for the DCP010505BP.

7.3.7 Load Regulation (10% to 100%)

The load regulation of the DCP01B series of devices is specified at 10% to 100% load. Placing a minimum 10% load will ensure the output voltage is within the range specified in Section 6.5. For more information regarding operation below 10% load, see Section 7.3.6.

7.3.8 Construction

The basic construction of the DCP01B series of devices is the same as standard integrated circuits. The molded package contains no substrate. The DCP01B series of devices are constructed using an IC, rectifier diodes, and a wound magnetic toroid on a lead frame. Because the package contains no solder, the devices do not require any special printed circuit board (PCB) assembly processing. This architecture results in an isolated DC/DC converter with inherently high reliability.

7.3.9 Thermal Management

Due to the high power density of these devices, it is advisable to provide ground planes on the input and output rails.

7.3.10 Power-Up Characteristics

The DCP01B series of devices do not include a soft-start feature. Therefore, a high in-rush current during power up is expected. Refer to the DCPA1 series of devices for a 1-W, isolated, unregulated DC/DC converter module with soft start included. Figure 7-3 shows the typical start-up waveform for a DCP010505BP, operating from a 5- V input with no load on the output. Figure 7-4 shows the start-up waveform for a DCP010505BP starting up into a 10% load. Figure 7-5 shows the start-up waveform starting up into a full (100%) load. Figure 7-3.

7.4 Device Functional Modes

7.4.1 Disable and Enable (SYNCIN Pin)

Each of the DCP01B series devices can be disabled or enabled by driving the SYNCIN pin using an open-drain CMOS gate. If the SYNCIN pin is pulled low, the DCP01B becomes disabled. The disable time depends upon the external loading. The internal disable function is implemented within 2 μs. Removal of the pulldown causes the DCP01B to be enabled. Capacitive loading on the SYNCIN pin must be minimized (≤ 3 pF) to prevent a reduction in the oscillator frequency. The application report External Synchronization of the DCP01/02 Series of DC/DC Converters describes disable and enable control circuitry.

7.4.2 Decoupling

7.4.2.1 Ripple Reduction

The high switching frequency of 400 kHz allows simple filtering. To reduce ripple, it is recommended that a minimum of 1-μF capacitor be used on the +VOUT pin. For dual output devices, decouple both of the outputs to the COM pin. The required 2.2-μF, low ESR ceramic input capacitor also helps reduce ripple and noise, (24-V input voltage versions require only 0.47 µF of input capacitance). See application report DC-to-DC Converter Noise Reduction.

7.4.2.2 Connecting the DCP01B in Series

Multiple DCP01B isolated 1-W DC/DC converters can be connected in series to provide non-standard voltage rails. This configuration is possible by using the floating outputs provided by the galvanic isolation of the DCP01. Connect the +VOUT from one DCP01B to the –VOUT of another (see Figure 7-6). If the SYNCIN pins are tied together, the self-synchronization feature of the DCP01B prevents beat frequencies on the voltage rails. The synchronization feature of the DCP01B allows easy series connection without external filtering, thus minimizing cost.

7.4.2.3 Connecting the DCP01B in Parallel

If the output power from one DCP01B is not sufficient, it is possible to parallel the outputs of multiple DCP01Bs, as shown in Figure 7-8 (applies to single output devices only).

8.2.4 PCB Design

The copper losses (resistance and inductance) can be minimized by the use of mutual ground and power planes (tracks) where possible. If that is not possible, use wide tracks to reduce the losses. If several devices are being powered from a common power source, a star-connected system for the track must be deployed. Do not connect the devices in series, because that type of connection cascades the resistive losses. The position of the decoupling capacitors is important. They must be as close to the devices as possible in order to reduce losses. See Section 10 for more details.

8.2.5 Decoupling Ceramic Capacitors

All capacitors have losses because of internal equivalent series resistance (ESR), and to a lesser degree, equivalent series inductance (ESL). Values for ESL are not always easy to obtain. However, some manufacturers provide graphs of frequency versus capacitor impedance. These graphs typically show the capacitor impedance falling as frequency is increased (as shown in Figure 8-4). In Figure 8-4, XC is the reactance due to the capacitance, X L is the reactance due to the ESL, and f0 is the resonant frequency. As the frequency increases, the impedance stops decreasing and begins to rise. The point of minimum impedance indicates the resonant frequency of the capacitor. This frequency is where the components of capacitance and inductance reactance are of equal magnitude. Beyond this point, the capacitor is not effective as a capacitor. Frequency (Hz) Capacitor Impedance (Ÿ ) XC XL Z Figure 8-4. Capacitor Impedance versus Frequency However, there is a 180° phase difference resulting in cancellation of the imaginary component. The resulting effect is that the impedance at the resonant point is the real part of the complex impedance, namely, the value of www.ti.com DCP010505B, DCP010512B, DCP010515B, DCP012405B, DCP010505DB, DCP010507DB, DCP010512DB, DCP010515DB, DCP011512DB, DCP011515DB, DCP012415DB SBVS012I – DECEMBER 2000 – REVISED SEPTEMBER 2020 Copyright © 2020 Texas Instruments Incorporated Submit Document Feedback 19 Product Folder Links: DCP010505B DCP010512B DCP010515B DCP012405B DCP010505DB DCP010507DB DCP010512DB DCP010515DB DCP011512DB DCP011515DB DCP012415DB

the ESR. The output capacitor's resonant frequency must be higher than the default switching frequency (800 kHz) of the device to properly decouple noise at and below the switching frequency.

The effect of the ESR is to cause a voltage drop within the capacitor. The value of this voltage drop is simply the product of the ESR and the transient load current, as shown in Equation 1. VIN = VPK – (ESR × ITR) (1) where

  • V IN is the voltage at the device input
  • V PK is the maximum value of the voltage on the capacitor during charge
  • I TR is the transient load current The other factor that affects the performance is the value of the capacitance. However, for the input and the full wave outputs (single-output voltage devices), ESR is the dominant factor.

8.2.6 Input Capacitor and the Effects of ESR

If the input decoupling capacitor is not ceramic (and has an ESR greater than 20 mΩ), then at the instant the power transistors switch on, the voltage at the input pins falls momentarily. If the voltage falls below approximately 4 V, the device detects an undervoltage condition and switches the internal drive circuits to a momentary off state. This detection is carried out as a precaution against a genuine low input voltage condition that could slow down or even stop the internal circuits from operating correctly. A slow-down or stoppage results in the drive transistors being turned on too long, causing saturation of the transformer and destruction of the device. Following detection of a low input voltage condition, the device switches off the internal drive circuits until the input voltage returns to a safe value, at which time the device tries to restart. If the input capacitor is still unable to maintain the input voltage, shutdown recurs. This process repeats until the input capacitor charges sufficiently to start the device correctly. Normal start-up should occur in approximately 1 ms after power is applied to the device. If a considerably longer start-up duration time is encountered, it is likely that either (or both) the input supply or the capacitors are not performing adequately. For 5-V to 15-V input devices, a 2.2-μF, low-ESR ceramic capacitor ensures good startup performance. For 24-V input voltage devices, 0.47-μF ceramic capacitors are recommended. Tantalum capacitors are not recommended, since most do not have low-ESR values and will degrade performance. If tantalum capacitors must be used, close attention must be paid to both the ESR and voltage as derated by the vendor. Note During the start-up period, these devices may draw maximum current from the input supply. If the input voltage falls below approximately 4 V, the devices may not start up. Connect a 2.2-μF ceramic capacitor close to the input pins.

8.2.7 Ripple and Noise

A good quality, low-ESR ceramic capacitor placed as close as practical across the input reduces reflected ripple and ensures a smooth start-up. A good quality, low-ESR ceramic capacitor placed as close as practical across the rectifier output terminal and output ground gives the best ripple and noise performance. See application report DC-to-DC Converter Noise Reduction for more information on noise rejection.

8.2.7.1 Output Ripple Calculation Example

The following example shows that increasing the capacitance has a much smaller effect on the output ripple voltage than does reducing the value of the ESR for the filter capacitor. To calculate the output ripple for a DCP010505 device:

  • V OUT = 5 V
  • I OUT = 0.2 A www.ti.com DCP010505B, DCP010512B, DCP010515B, DCP012405B, DCP010505DB, DCP010507DB, DCP010512DB, DCP010515DB, DCP011512DB, DCP011515DB, DCP012415DB SBVS012I – DECEMBER 2000 – REVISED SEPTEMBER 2020 Copyright © 2020 Texas Instruments Incorporated Submit Document Feedback 21 Product Folder Links: DCP010505B DCP010512B DCP010515B DCP012405B DCP010505DB DCP010507DB DCP010512DB DCP010515DB DCP011512DB DCP011515DB DCP012415DB
  • At full output power, the load resistor is 25 Ω
  • Ceramic output capacitor of 1 μF, ESR of 0.1 Ω
  • Capacitor discharge time 1% of 800 kHz (ripple frequency) tDIS = 0.0125 μs τ = C × RLOAD τ = 1 × 10-6 × 12.5 = 12.5 μs VDIS = VO(1 – EXP(–tDIS / τ)) VDIS = 5 mV By contrast, the voltage dropped because of ESR: VESR = ILOAD × ESR VESR = 20 mV Ripple voltage = 25 mV

8.2.8 Dual DCP01B Output Voltage

The voltage output for dual DCP01B devices is half wave rectified; therefore, the discharge time is 1.25 μs. Repeating the above calculations using the 100% load resistance of 50 Ω (0.1 A per output), the results are: τ = 25 μs tDIS = 1.25 μs VDIS = 244 mV VESR = 10 mV Ripple Voltage = 133 mV This time, it is the capacitor discharging that contributes to the largest component of ripple. Changing the output filter to 10 μF, and repeating the calculations, the result is: Ripple voltage = 25 mV This value is composed of almost equal components. The previous calculations are offered as a guideline only. Capacitor parameters usually have large tolerances and can be susceptible to environmental conditions.

8.2.9 Optimizing Performance

Optimum performance can only be achieved if the device is correctly supported. The very nature of a switching converter requires power to be instantly available when it switches on. If the converter has DMOS switching transistors, the fast edges will create a high current demand on the input supply. This transient load placed on the input is supplied by the external input decoupling capacitor, thus maintaining the input voltage. Therefore, the input supply does not see this transient (this is an analogy to high-speed digital circuits). The positioning of the capacitor is critical and must be placed as close as possible to the input pins and connected via a low- impedance path. The optimum performance primarily depends on two factors:

  • Connection of the input and output circuits for minimal loss.
  • The ability of the decoupling capacitors to maintain the input and output voltages at a constant level.

9 Power Supply Recommendations

The DCP01B is a switching power supply, and as such can place high peak current demands on the input supply. To avoid the supply falling momentarily during the fast switching pulses, ground and power planes must be used to connect the power to the input of DCP01 device. If this connection is not possible, then the supplies must be connected in a star formation with the traces made as wide as possible.

10 Layout

10.1 Layout Guidelines

Due to the high power density of these devices, provide ground planes on the input and output rails. Figure 10-1 and Figure 10-2 show the schematic for the two DIP through-hole packages, and two SOP surface- mount packages for the DCP family of products which include DCP01B, DCP02, DCV01, DCR01, and DCR02. Figure 10-3 and Figure 10-4 illustrate a printed circuit board (PCB) layout for the schematics. Including input power and ground planes provides a low-impedance path for the input power. For the output, the COM signal connects via a ground plane, while the connections for the positive and negative voltage outputs conduct via wide traces in order to minimize losses. The output should be taken from the device using ground and power planes, thereby ensuring minimum losses. The location of the decoupling capacitors in close proximity to their respective pins ensures low losses due to the effects of stray inductance, thus improving the ripple performance. This location is of particular importance to the input decoupling capacitor, because this capacitor supplies the transient current associated with the fast switching waveforms of the power drive circuits. Allow the unused SYNC pin, to remain configured as a floating pad. It is advisable to place a guard ring (connected to input ground) or annulus connected around this pin to avoid any noise pick up. When connecting a SYNC pin to one or more SYNC design the linking trace to be short and narrow to avoid stray capacitance. Ensure that no other trace is in close proximity to this trace SYNC trace to decrease the stray capacitance on this pin. The stray capacitance affects the performance of the oscillator.

www.ti.com 17-Jun-2025 (2) Material type: When designated, preproduction parts are prototypes/experimental devices, and are not yet approved or released for full production. Testing and final process, including without limitation quality assurance, reliability performance testing, and/or process qualification, may not yet be complete, and this item is subject to further changes or possible discontinuation. If available for ordering, purchases will be subject to an additional waiver at checkout, and are intended for early internal evaluation purposes only. These items are sold without warranties of any kind. (3) RoHS values: Yes, No, RoHS Exempt. See the TI RoHS Statement for additional information and value definition. (4) Lead finish/Ball material: Parts may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two lines if the finish value exceeds the maximum column width. (5) MSL rating/Peak reflow: The moisture sensitivity level ratings and peak solder (reflow) temperatures. In the event that a part has multiple moisture sensitivity ratings, only the lowest level per JEDEC standards is shown. Refer to the shipping label for the actual reflow temperature that will be used to mount the part to the printed circuit board. (6) Part marking: There may be an additional marking, which relates to the logo, the lot trace code information, or the environmental category of the part. Multiple part markings will be inside parentheses. Only one part marking contained in parentheses and separated by a "~" will appear on a part. If a line is indented then it is a continuation of the previous line and the two combined represent the entire part marking for that device.
