Overview
The PTH12060WAH is a non-isolated power module from Texas Instruments, part of the PTH12060 series. This module is designed as a complete dc/dc converter, offering a compact solution for applications requiring up to 10 A of load current. The module operates from a 12-V input bus voltage and provides step-down power conversion to a wide range of output voltages, adjustable from 1.2 V to 5.5 V. Its small footprint of 1 inch × 0.62 inch makes it suitable for space-conscious digital systems, including those with multiple processors.
