Description

The PTH12000 series of non-isolated power modules are small in size and high on performance. Using double-sided sur- face mount construction and synchronous rectification technology, these regulators deliver up to 6 A of output current while occupying a PCB area of about half the size of a standard postage stamp. They are an ideal choice for applications where space, performance and cost are impor- tant design constraints. The series operates from an input volt- age of 12 V to provide step-down power conversion to a wide range of output volt- ages. W-suffix devices are adjustable from 1.2 V to 5.5 V , and L-suffix devices are adjustable from 0.8 V to 1.8 V . The out- put voltage is set within the adjustment range using a single external resistor. Operating features include an on/off inhibit, output voltage adjust (trim), and the ability to start up into an existing output voltage or prebias. A non-latching over-current trip provides protection against load faults. T arget applications include telecom, industrial, and general purpose circuits, including low-power dual-voltage systems that use a DSP , microprocessor, or ASIC. Package options include both through- hole and surface mount configurations. Pin Configuration Pin Function

For technical support and further information visit http://power.ti.com Pin Descriptions Vin: The positive input voltage power node to the mod- ule, which is referenced to common GND. Vout: The regulated positive power output with respect to the GND node. GND: This is the common ground connection for the ‘Vin’ and ‘Vout’ power connections. It is also the 0 VDC reference for the ‘Inhibit’ and ‘V o Adjust’ control inputs. Inhibit: The Inhibit pin is an open-collector/drain negative logic input that is ref erenced to GND. Applying a low- level ground signal to this input disables the module’ s output and turns off the output voltage. When the Inhibit control is active, the input current drawn by the regulator is significantly reduced. If the Inhibit pin is left open- circuit, the module will produce an output whenever a valid input source is applied. Vo Adjust: A 1-% resistor must be connected between this pin and GND (pin 1) to set the output voltage of the module higher than its lowest value. The temperature stability of the resistor should be 100 ppm/°C (or better). The set-point range is 1.2 V to 5.5 V for W-suffix devices, and 0.8 V to 1.8 V for L-suffix devices. The resistor value required for a given output voltage may be calculated using a formula. If left open circuit, the output voltage will default to its lowest value. For further information on output voltage adjustment consult the related applica- tion note. The specification tables also give the preferred resistor values for a number of standard output voltages.

For technical support and further information visit http://power.ti.com Capacitor Recommendations for the PTH12000 Wide-Output Adjust Power Modules Input Capacitor The recommended input capacitance is determined by the 100 μF minimum capacitance and 750 mArms mini- mum ripple current rating. A 10-μF X5R/X7R ceramic capacitor may also be added to reduce the reflected input ripple current [3]. The ceramic capacitor should be located between the input electrolytic and the module. Ripple current, less than 150 m Ω equivalent series resis- tance (ESR) and temperature are major considerations when selecting input capacitors. Unlike polymer-tantalum capacitors, regular tantalum capacitors have a recom- mended minimum voltage rating of 2 × (max. DC voltage + AC ripple). This is standard practice to ensure reliability. No tantalum capacitors were found with sufficient volt- age rating to meet this requirement. At temperatures below 0 °C, the ESR of alumi num electrolytic capacitors increases. For these applications Os-Con, polymer-tan- talum, and polymer-aluminum types should be considered. Output Capacitors (Optional) For applications with load transients (sudden changes in load current), regulator response will benefit from external output capacitance. The value of 100 μF is used to define the transient response specification (see data sheet). For most applications, a high quality computer-grade alumi- num electrolytic capacitor is adequate. These capacitors provide decoupling over the frequency range, 2 kHz to 150 kHz, and are suitable for ambient temperatures above 0 °C. Below 0 °C, tantalum, ceramic or Os-Con type capacitors are recommended. When using one or more non-ceramic capacitors, the calculated equivalent ESR should be no lower than 4 mΩ (7 mΩ using the manufacturer’s maximum ESR for a single capacitor). A list of preferred low-ESR type capacitors are identified in T able 1-1. In addition to electrolytic capacitance, adding a 10-μF X5R/X7R ceramic capacitor to the output will reduce the output ripple voltage and improve the regulator’s transient response. The measurement of both the output ripple and transient response is also best achieved across a 10-μF ceramic capacitor. Ceramic Capacitors Above 150 kHz the performance of aluminum electrolytic capacitors is less effective. Multilayer ceramic capacitors have very low ESR and a resonant frequency higher than the bandwidth of the regulator. They can be used to reduce the reflected ripple current at the input [3] and improve the transient response of the output. When used on the output their combined ESR is not critical as long as the total value of ceramic capacitance does not exceed 300 μF. Also, to prevent the formation of local resonances, do not place more than five identical ceramic capacitors in par- allel with values of 10 μF or greater. Tantalum Capacitors T antalum type capacitors are most suited for use on the output bus, and are recommended for applications where the ambient operating temperature can be less than 0 °C. The AVX TPS, Sprague 593D/594/595 and Kemet T495/ T510 capacitor series are suggested over other tantalum types due to their higher rated surge, power dissipation, and ripple curr ent capability. As a caution many general purpose tantalum capacitors have considerably higher ESR, reduced power dissipation and lower ripple current capability. These capacitors are also less reliable as they have lower power dissipation and surge current ratings. T antalum capacitors that do not have a stated ESR or surge current rating are not recommended for power applications. When specifying Os-con and polymer tantalum capacitors for the output, the minimum ESR limit will be encoun- tered well before the maximum capacitance value is reached. Capacitor Table T able 1-1 identifies the characteristics of capacitors from a number of vendors with acceptable ESR and ripple current (rms) ratings. The recommended number of capacitors required at both the input and output buses is identified for each capacitor type. This is not an extensive capacitor list. Capacitors from other vendors are available with comparable specifications. Those listed are for guidance. The RMS ripple current rating and ESR (at 100 kHz) are critical parameters necessary to insure both optimum regulator performance and long capacitor life. Designing for Very Fast Load Transients The transient response of the DC/DC converter has been characterized using a load transient with a di/dt of 1 A/μs. The typical voltage deviation for this load transient is given in the data sheet specification table using the optional value of output capacitance. As the di/dt of a transient is increased, the response of a converter’s regulation circuit ultimately depends on its output capacitor decoupling network. This is an inherent limitation with any DC/DC con verter once the speed of the transient exceeds its bandwidth capability. If the target application specifies a higher di/dt or lower volt- age deviation, the requirement can only be met with additional output capacitor decoupling. In these cases special attention must be paid to the type, value and ESR of the capacitors selected. If the transient performance requirements exceed that specified in the data sheet, the selection of output ca- pacitors becomes more important. PTH12000 Series

For technical support and further information visit http://power.ti.com Adjusting the Output Voltage of the PTH12000x Wide-Output Adjust Power Modules The Vo Adjust control (pin 4) sets the output voltage of the PTH12000 product. The adjustment range is from 1.2 V to 5.5 V for the W-suffix modules, and 0.8 V to 1.8 V for L-suffix modules. The adjustment method requires the addition of a single external resistor, R set, that must be connected dir ectly between the Vo Adjust and GND pins 1. T able 2-1 gives the preferred value of the external resistor for a number of standard voltages, along with the actual output voltage that this resistance value provides. Figure 2-1 shows the placement of the required resistor. Figure 2-1; Vo Adjust Resistor Placement Notes: 1. A 0.05-W rated resistor may be used. The tolerance should be 1 %, with a temperature stability of 100 ppm/°C or better. Place the resistor as close to the regulator as possible.

For technical support and further information visit http://power.ti.com Pre-Bias Startup Capability The capability to start up into an output pre-bias condi- tion is now a feature of the PTH12000 series of modules. (Note: This is a feature enhancement for the the W-suffix version; see note 1). A pre-bias startup condition occurs as a result of an external voltage being present at the output of a power module prior to its output becoming active. This often occurs in com- plex digital systems when current from another power source is backfed through a dual-supply logic component, such as an FPGA or ASIC. Another path might be via clamp diodes, sometimes used as part of a dual-supply power-up sequencing arrangement. A pr ebias can cause problems with power modules that incorporate synchro- nous rectifiers. This is because under most operating conditions, such modules can sink as well as source output current. The PTH12000x series of modules incorporate synchronous rectifiers, but will not sink current during startup, or whenever the Inhibit pin is held low. Startup includes an initial delay (approx. 8 - 15 ms), followed by the rise of the output voltage under the control of the module’s internal soft-start mechanism; see Figure 3-1. Conditions for Pre-Bias Holdoff In order for the module to allow an output pre-bias voltage to exist (and not sink current), certain conditions must be maintained. The module holds off a pre-bias voltage when the Inhibit pin is held low, and whenver the output is allowed to rise under soft-start control. Power up under soft-start control occurs upon the removal of the ground signal to the Inhibit pin (with input voltage applied), or when input power is applied. T o fur ther ensure that the regulator doesn’t sink output current, (even with a ground signal applied to its Inhibit), the input voltage must always be greater than the applied pre-bias source. This condi- tion must exist throughout the power-up sequence The soft-start period is complete when the output begins rising above the pre-bias voltage. Once it is complete the module functions as normal, and will sink current if a voltage higher than the nominal regulation value is applied to its output. Note: If a pre-bias condition is not present, the soft-start period will be complete when the output voltage has risen to either the set-point voltage. Demonstration Circuit The circuit shown in Figure 3-4 is a demonstrates the pre-bias startup feature. Figure 3-5 shows the startup waveforms. The initial rise in Vo 2 is the pre-bias volt- age, which is passed from the VCCIO to the VCORE voltage rail through the ASIC. Note that the output cur- rent from the PTH12000L module (Io 2) is negligible until its output voltage rises above the applied pre-bias.

Output pre-bias holdoff has now been incorporated into the W-suffix modules (PTH12000W), with a production lot date code of “0423” or later. 2. T o further ensure that the r egulator’s output does not sink current when power is first applied (even with a ground signal applied to the Inhibit control pin), the input voltage must always be greater than the applied pre-bias source. This condition must exist throughout the power-up sequence of the power system.
