Description for the PTH12040W
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.
