The TPSM53603 power module is a highly integrated 3-A power solution that 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 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 TPSM53603 an excellent device for powering a wide range of applications.
