The TPSM63603 power module is a highly integrated3-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 30-pin QFN packagehas enhanced thermal performance, small footprint,and low EMI. The package footprint has all signal andpower pins accessible from the perimeter as well asfour larger thermal pads beneath the device for simplelayout and easy handling in manufacturing.

The TPSM63603 is a compact, easy-to-use powermodule with a wide output voltage range of 1.0 V to16 V. The module is designed to quickly and easilyimplement a power design in a small PCB footprint.
