8 V to 36 Vin Cool-Power ZVS Buck Regulator Family

Cool-Power® PI33xx-x0 Product Description The PI33xx-x0 is a family of high efficiency, wide input range DC-DC ZVS-Buck regulators integrating controller, power switches, and support components all within a high density System-in-Package (SiP). The integration of a high performance Zero-Voltage Switching (ZVS) topology, within the PI33xx-x0 series, increases point of load performance providing best in class power efficiency. The PI33xx-x0 requires only an external inductor and minimal capacitors to form a complete DC-DC switching mode Buck Regulator. The ZVS architecture also enables high frequency operation while minimizing switching losses and maximizing efficiency. The high switching frequency operation reduces the size of the external filtering components, improves power density, and enables very fast dynamic response to line and load transients. The PI33xx-x0 series sustains high switching frequency all the way up to the rated input voltage without sacrificing efficiency and, with its 20 ns minimum on-time, supports large step down conversions up to 36 Vin. *I2C is a trademark of NXP Semiconductors Features & Benefits

Cool-Power® Rev 2.0 vicorpower.com Page 32 of 42 02/2016 800 927.9474 PI33xx-x0 Functional Description The PI33xx-x0 is a family of highly integrated ZVS-Buck regulators. The PI33xx-x0 has a set output voltage that is trimmable within a prescribed range shown in Table 1. Performance and maximum output current are characterized with a specific external power inductor (see Table 4). For basic operation, Figure 58 shows the connections and compo - nents required. No additional design or settings are required. ENABLE (EN) EN is the enable pin of the converter. The EN Pin is referenced to SGND and permits the user to turn the regulator on or off. The EN default polarity is a positive logic assertion. If the EN pin is left floating or asserted high, the converter output is enabled. Pulling EN pin below 0.8 Vdc with respect to SGND will disable the regu - lator output. The EN input polarity can be programmed (PI33xx-20 device versions only) via the I2C data bus. When the EN pin polarity is programmed for negative logic assertion; and if the EN pin is left floating, the regulator output is enabled. Pulling the EN pin above 1.0 Vdc with respect to SGND, will disable the regulator output. Remote Sensing An internal 100 Ω resistor is connected between REM pin and VOUT pin to provide regulation when the REM connection is broken. Referring to Figure 58, it is important to note that L1 and COUT are the output filter and the local sense point for the power supply output. As such, the REM pin should be connected at COUT as the default local sense connection unless remote sensing to compensate additional distribution losses in the system. The REM pin should not be left floating. Switching Frequency Synchronization The SYNCI input allows the user to synchronize the controller switching frequency by an external clock referenced to SGND. The external clock can synchronize the unit between 50% and 110% of the preset switching frequency (fS). For PI33xx-20 device versions only, the phase delay can be programmed via I2C bus with respect to the clock applied at SYNCI pin. Phase delay allows PI33xx-20 regulators to be paralleled and operate in an interleaving mode. The PI33xx-x0 default for SYNCI is to sync with respect to the falling edge of the applied clock providing 180° phase shift from SYNCO. This allows for the paralleling of two PI33xx-x0 devices without the need for further user programming or external sync clock circuitry. The user can change the SYNCI polarity to sync with the external clock rising edge via the I2C data bus (PI33xx-20 device versions only). When using the internal oscillator, the SYNCO pin provides a 5 V clock that can be used to sync other regulators. Therefore, one PI33xx-x0 can act as the lead regulator and have additional PI33xx-x0s running in parallel and interleaved. Soft-Start The PI33xx-x0 includes an internal soft-start capacitor to ramp the output voltage in 2 ms from 0 V to full output voltage. Connect- ing an external capacitor from the TRK pin to SGND will increase the start-up ramp period. See, “Soft Start Adjustment and Track,” in the Applications Description section for more details. Output Voltage Trim The PI33xx-x0 output voltage can be trimmed up from the preset output by connecting a resistor from ADJ pin to SGND and can be trimmed down by connecting a resistor from ADJ pin to VOUT. The Table 1 defines the voltage ranges for the PI33xx-x0 family.

Cool-Power® Rev 2.0 vicorpower.com Page 33 of 42 02/2016 800 927.9474 PI33xx-x0 Output Current Limit Protection PI33xx-x0 has two methods implemented to protect from output short or over current condition. Slow Current Limit protection: prevents the output load from sourcing current higher than the regulator’s maximum rated current. If the output current exceeds the Current Limit (IOUT_CL) for 1024 us, a slow current limit fault is initiated and the regulator is shutdown which eliminates output current flow. After Fault Restart Delay (tFR_DLY ), a soft-start cycle is initiated. This restart cycle will be repeated indefinitely until the excessive load is removed. Fast Current Limit protection: PI33xx-x0 monitors the regulator inductor current pulse-by-pulse to prevent the output from supplying very high current due to sudden low impedance short (50 A Typical). If the regulator senses a high inductor current pulse, it will initiate a fault and stop switching until Fault Restart Delay ends and then initiate a soft-start cycle. Both the Fast and Slow current limit faults are stored in a Fault Register and can be read and cleared (PI33xx-20 device versions only) via I2C data bus. Input Undervoltage Lockout If VIN falls below the input Undervoltage Lockout (UVLO) threshold, but remains high enough to power the internal bias supply, the PI33xx-x0 will complete the current cycle and stop switching. If VIN recovers within 128 switching cycles, the PI33xx-x0 will resume normal operation. If this time limit is exceeded, the system will enter a low power state and initiate a fault.The system will restart once the input voltage is reestablished and after the Fault Restart Delay. A UVLO fault is stored in a Fault Register and can be read and cleared (PI33xx-20 device versions only) via I2C data bus. Input Overvoltage Lockout If VIN exceeds the input Overvoltage Lockout (OVLO) threshold (VOVLO), while the controller is running, the PI33xx-x0 will complete the current cycle and stop switching. If VIN recovers within 128 switching cycles, the PI33xx-x0 will resume normal operation. Otherwise, the system will enter a low power state and sets an OVLO fault. The system will resume operation when the input voltage falls below 98% of the OVLO threshold and after the Fault Restart Delay. The OVLO fault is stored in a Fault Register and can be read and cleared (PI33xx-20 device versions only) via I2C data bus. Output Overvoltage Protection The PI33xx-x0 family is equipped with output Overvoltage Protection (OVP) to prevent damage to input voltage sensitive devices. If the output voltage exceeds 20% of its set regulated value, the regulator will complete the current cycle, stop switching and issue an OVP fault. The system will resume operation once the output voltage falls below the OVP threshold and after Fault Restart Delay. The OVP fault is stored in a Fault Register and can be read and cleared (PI33xx-20 device versions only) via I2C data bus. Overtemperature Protection The internal package temperature is monitored to prevent internal components from reaching their thermal maximum. If the Over Temperature Protection Threshold (OTP) is exceeded (TOTP), the regulator will complete the current switching cycle, enter a low power mode, set a fault flag, and will soft-start when the internal temperature falls below Overtemperature Restart Hysteresis (TOTP_HYS). The OTP fault is stored in a Fault Register and can be read and cleared (PI33xx-20 device versions only) via I2C data bus. Pulse Skip Mode (PSM) PI33xx-x0 features a PSM to achieve high efficiency at light loads. The regulators are setup to skip pulses if EAO falls below a PSM threshold. Depending on conditions and component values, this may result in single pulses or several consecutive pulses followed by skipped pulses. Skipping cycles significantly reduces gate drive power and improves light load efficiency. The regulator will leave PSM once the EAO rises above the Skip Mode threshold. Variable Frequency Operation Each PI33xx-x0 is preprogrammed to a base operating frequency, with respect to the power stage inductor (see Table 4), to operate at peak efficiency across line and load variations. At low line and high load applications, the base frequency will decrease to accommodate these extreme operating ranges. By stretching the frequency, the ZVS operation is preserved throughout the total in - put line voltage range therefore maintaining optimum efficiency. Parallel Operation Paralleling modules can be used to increase the output current capability of a single power rail and reduce output voltage ripple.

This allows for the paralleling of two PI33xx-x0 devices without the need for further user programming or external sync clock circuitry. The user can change the SYNCI polarity to sync with the external clock rising edge via the I2C data bus (PI33xx-20 device versions only). By connecting the EAO pins and SGND pins of each module together the units will share the current equally. When the TRK pins of each unit are connected together, the units will track each other during soft-start and all unit EN pins have to be released to allow the units to start (See Figure 59). Also, any fault event in any regulator will disable the other regulators. The two regulators will be out of phase with each other reducing output ripple (refer to Switching Frequency Synchronization). To provide synchronization between regulators over the entire operational frequency range, the Parallel Good (PGD) pin must be connected to the lead regulator’s (#1) SYNCI pin and a 2.5 kΩ Resistor, R1, must be placed between SYNCO (#2) return and the lead regulator’s SYNCI (#1) pin, as shown in Figure 59. In this configuration, at system soft-start, the PGD pin pulls SYNCI low forcing the lead regulator to initialize the open-loop startup synchronization. Once the regulators reach regulation, SYNCI is released and the system is now synchronized in a closed-loop configuration which allows the system to adjust, on the fly, when any of the individual regulators begin to enter variable frequency mode in the loop. Multi-phasing three regulators is possible (PI33xx-20 only) with no change to the basic single-phase design. For more information about how to program phase delays within the regulator, please refer to Picor application note PI33xx-2x Multi-Phase Design Guide. I2C Interface Operation PI33xx-20 devices provide an I2C digital interface that enables the user to program the EN pin polarity (from high to low assertion) and switching frequency synchronization phase/delay. These are one time programmable options to the device. Also, the PI33xx-20 devices allow for dynamic VOUT margining via I2C that is useful during development (settings stored in volatile memory only and not retained by the device). The PI33xx-20 also have the option for fault telemetry including: nn Fast/Slow current limit nn Output voltage high nn Input overvoltage nn Input undervoltage nn Over temperature protection For more information about how to utilize the I2C interface please refer to Picor application note PI33xx-2x I2C Digital Interface Guide. Application Description Output Voltage Trim The PI33xx-x0 family of Buck Regulators provides seven common A post-package trim step is implemented to offset any resistor divider network errors ensuring maximum output accuracy. With a single resistor connected from the ADJ pin to SGND or REM, each device’s output can be varied above or below the nominal set voltage (with the exception of the PI3311-X0 which can only be above the set voltage of 1 V). The remote pin (REM) should always be connected to the VOUT pin, if not used, to prevent an output voltage offset. Figure 60 shows the internal feedback voltage divider network. R1, R2, and R4 are all internal 1.0 % resistors and Rlow and Rhigh are external resistors for which the designer can add to modify VOUT to a desired output. The internal resistor value for each regulator is listed below in Table 3. Table 2 — PI33xx-x0 family output voltage range - ADJ REM VOUT SGND Rlow Rhigh

This inductor has been optimized for maximum efficiency performance. Table 4 details the specific inductor value and part number utilized for each PI33xx-x0 device which are available from Coiltronics and Eaton. Data sheets are available at: http://www.cooperindustries.com Thermal Derating Thermal de-rating curves are provided that are based on component temperature changes versus load current, input voltage and air flow. It is recommended to use these curves as a guideline for proper thermal de-rating. These curves represent the entire system and are inclusive to both the Picor regulator and the external inductor. Maximum thermal operation is limited by either the MOSFETs or inductor depending upon line and load conditions. Thermal measurements were made using a standard PI33xx-x0 Evaluation board which is 3 x 4 inches in area and uses 4-layer, 2 oz copper. Thermal measurements were made on the three main power devices, the two internal MOSFETs and the external inductor, with air flows of 0, 200, and 400 LFM. Filter Considerations The PI33xx-x0 requires input bulk storage capacitance as well as low impedance ceramic X5R input capacitors to ensure proper start up and high frequency decoupling for the power stage. The PI33xx-x0 will draw nearly all of the high frequency current from the low impedance ceramic capacitors when the main high side MOSFET is conducting. During the time the high side MOSFET is off, they are replenished from the bulk capacitor. If the input impedance is high at the switching frequency of the converter, the bulk capacitor must supply all of the average current into the converter, including replenishing the ceramic capacitors. This value has been chosen to be 100 μF so that the PI33xx-x0 can start up into a full resistive load and supply the output capacitive load with the default minimum soft start capacitor when the input source impedance is 50 Ohms at 1 MHz. The ESR for this capacitor should be approximately 20 mΩ. The RMS ripple current in this capacitor is small, so it should not be a concern if the input recommended ceramic capacitors are used. Table 5 shows the recommended input and output capacitors to be used for the various models as well as expected transient response, RMS ripple currents per capacitor, and input and output ripple voltages. Table 6 includes the recommended input and output ceramic capacitors. Table 4 — PI33xx-x0 Inductor pairing Device VIN (V) ILOAD (A) CINPUT Ceramic X5R CINPUT Bulk Elec.
