3 Description

The TPSM5601R5Hx power module is a highly

integrated 1.5-A power solution that combines a 60-

V input, step-down DC/DC converter with power

MOSFETs, a shielded inductor, and passives in

a thermally-enhanced QFN package. The 5-mm

× 5.5-mm × 4-mm, 15-pin QFN package uses

Enhanced HotRod QFN technology for enhanced

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 TPSM5601R5Hx is a compact, easy-to-use

power module with a wide adjustable output voltage

range of 1.0 V to 16 V. 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 temperature protections,

making the TPSM5601R5Hx an excellent device

for powering a wide range of applications. Spaceconstrained

applications benefit from the 5-mm × 5.5-

mm package. Additionally, the TPSM5601R5HEXT

offers extended low temperature operation of –55°C

and the TPSM5601R5HS offers frequency spreadspectrum

operation.
