MAXM17543
MAXM17543
4.5V to 42V, 2.5A 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 MAXM17543 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 42V and delivers up to 2.5A 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, reducing 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 MAXM17543 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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
