UL/cUL 60950, EN60950, VDEThe PTH12040Wisa high-performance 50-A rated, non-isolated, power module, which uses the latest
multiphase switched-mode topology. This providesa small, ready-to-use module, that can power the most densly
populated multiprocessor systems.
Operating from an input voltage rangeof8Vto14V, the PTH12040W requiresa single resistorto set the output
voltageto any value over the range, 0.8Vto 5.5V. The wide input voltage range makes the PTH12040W
particularly suitable for advanced computing and server applications that utilizea loosely regulated 12-V
intermediate distribution bus.
The modules incorporatea comprehensive listof 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 thresholdstobe customized.
The PTH12040W incorporates Auto-Track™. The Auto-Track featureof the PTH family allows the outputsof
multiple modulesto tracka common voltage during power up and power down transitions. This simplifies power and power down supply-voltage sequencingina power supply system.
The modules use double-sided surface mount constructionto providea low profile and compact footprint.
Package options include both through-hole and surface mount configurations.
