Overview
The TPSM53602RDAR power module from Texas Instruments is a highly integrated 2-A power solution designed for a wide range of applications. It combines a 36-V input, step-down DC/DC converter with power MOSFETs, a shielded inductor, and passives in a thermally-enhanced QFN package. The module features Texas Instruments' Enhanced HotRod QFN technology, which provides improved thermal performance, a small footprint, and low EMI. This package is designed for simplicity in layout and easy handling in manufacturing, requiring as few as four external components and eliminating the need for loop compensation and magnetics part selection.
