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.
