Overview
The PTH12040WAZ is a high-performance, 50-A rated, non-isolated power module produced by Texas Instruments. This module utilizes the latest multiphase switched-mode topology, making it suitable for powering densely populated multiprocessor systems. It operates from an input voltage range of 8 V to 14 V and can be adjusted to output voltages between 0.8 V and 5.5 V using a single resistor. The module is particularly suited for advanced computing and server applications that use a loosely regulated 12-V intermediate distribution bus.
