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.
