MAXM17504
EVALUATION KIT AVAILABLE
4.5V to 60V, 3.5A High-Efficiency, DC-DC
Step-Down Power Module with Integrated Inductor
General Description
The Himalaya series of voltage regulator ICs and Power
Modules enable cooler, smaller and simpler power supply
solutions. The MAXM17504 is an easy-to-use, step-down
power module that combines a switching power supply
controller, dual n-channel MOSFET power switches, fully
shielded inductor, and the compensation components in
a low-profile, thermally-efficient, system-in-package (SiP).
The device operates over a wide input voltage range of
4.5V to 60V and delivers up to 3.5A continuous output
current with excellent line and load regulation over an
output voltage range of 0.9V to 12V. The device only
requires five external components to complete the total
power solution. The high level of integration significantly
reduces design complexity, manufacturing risks, and
offers a true plug-and-play power supply solution, reduc-
ing time-to-market.
The device can be operated in the pulse-width
modulation (PWM), pulse-frequency modulation (PFM), or
discontinuous conduction mode (DCM) control schemes.
The MAXM17504 is available in a low-profile, highly
thermal-emissive, compact, 29-pin 9mm x 15mm x
2.8mm SiP package that reduces power dissipation in
the package and enhances efficiency. The package is
easily soldered onto a printed circuit board and suitable
for automated circuit board assembly. The device can
operate over the industrial temperature range from -40°C
to +125°C.
