General Description

The Himalaya series of voltage regulator ICs, power

modules, and chargers enable cooler, smaller, and sim-

pler power supply solutions. The MAXM17543 is an

easy-to-use Himalaya, step-down power module that

combines a switching power supply controller, dual

n-channel MOSFET power switches, fully shielded induc-

tor, and the compensation components in a low-pro-

file, 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

currentwithexcellentlineandloadregulationoveranoutput

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.
