SLTS237G – DECEMBER 2004 – REVISED MARCH 2009 ADJUST POWER MODULE • Advanced Computing and Server Applications 2 • 50-A Output Current • 8-V to 14-V Input Voltage • Wide-Output Voltage Adjust (0.8 V to 5.5 V) • Efficiencies up to 96% • On/Off Inhibit • Differential Output Sense • Output Overcurrent Protection (Nonlatching, Auto-Reset) • Overtemperature Protection • Auto-Track™ Sequencing • Start Up Into Output Prebias • Margin Up/Down Controls • Operating Temperature: –40°C to 85°C • Multi-Phase, Switch-Mode Topology • Programmable Undervoltage Lockout (UVLO) • Safety Agency Approvals: UL/cUL 60950, EN60950, VDE The PTH12040W is a high-performance 50-A rated, non-isolated, power module, which uses the latest multiphase switched-mode topology. This provides a small, ready-to-use module, that can power the most densly populated multiprocessor systems. Operating from an input voltage range of 8 V to 14 V, the PTH12040W requires a single resistor to set the output voltage to any value over the range, 0.8 V to 5.5 V. The wide input voltage range makes the PTH12040W particularly suitable for advanced computing and server applications that utilize a loosely regulated 12-V intermediate distribution bus. The modules incorporate a comprehensive list of features. They include on/off inhibit and margin up/down controls. A differential remote output voltage sense ensures tight load regulation, and an output overcurrent and overtemperature shutdown protect against most load faults. The programmable under-voltage lockout allows the turn-on and turn-off voltage thresholds to be customized. The PTH12040W incorporates Auto-Track™. The Auto-Track feature of the PTH family allows the outputs of multiple modules to track a common voltage during power up and power down transitions. This simplifies power up and power down supply-voltage sequencing in a power supply system. The modules use double-sided surface mount construction to provide a low profile and compact footprint. Package options include both through-hole and surface mount configurations. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 Auto-Track, POLA, TMS320 are trademarks of Texas Instruments.
