DESCRIPTION

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.

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.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
