3 Description

The TPSM53602 power module is a highly integrated

2-A power solution that combines a 36-V input,

step-down, DC/DC converter with power MOSFETs,

a shielded inductor, and passives in a thermallyenhanced

QFN package. The 5-mm x 5.5-mm x 4-

mm, 15-pin package uses Enhanced HotRod QFN

technology for improved thermal performance, small

footprint, and low EMI. The package footprint has all

pins accessible from the perimeter and a single large

thermal pad for simple layout and easy handling in

manufacturing.

The total solution requires as few as four

external components and eliminates the loop

compensation and magnetics part selection from

the design process. The full feature set includes

power good, programmable UVLO, prebias start-up,

overcurrent, and overtemperature protections, making

the TPSM53602 an excellent device for powering a

wide range of applications.
