Overview
The PTH12040WAH is a high-performance, 50-A rated, non-isolated power module produced by Texas Instruments. It utilizes the latest multiphase switched-mode topology, making it suitable for powering densely populated multiprocessor systems. The module operates from an input voltage range of 8 V to 14 V and allows the output voltage to be adjusted to any value between 0.8 V and 5.5 V using a single resistor. This wide input voltage range and adjustable output make it particularly suitable for advanced computing and server applications that use a loosely regulated 12-V intermediate distribution bus.
