Overview
The PTH12060LAH 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 PTH12060LAH features a small footprint of 1 inch × 0.62 inch (25.4 mm × 15.7 mm) and is suitable for space-conscious digital systems that incorporate multiple processors. It operates from a 12-V input bus voltage and provides step-down power conversion to a wide range of output voltages, specifically adjustable between 0.8 V and 1.8 V for the L-suffix devices.
