General Description

The Himalaya series of voltage regulator ICs, power modules,

and chargers enable cooler, smaller, and simpler

power-supply solutions. The MAXM17572 is a high-efficiency,

synchronous, Himalaya step-down DC-DC power

module with integrated controller, MOSFETs, compensation

components, and inductor that operates over a wide

input-voltage range. The module operates from 4.5V to

60V input and delivers up to 1A output current over a programmable

output voltage range of 0.9V to 12V. The module

significantly reduces design complexity and manufacturing

risks, and offers a true “plug-and-play” power supply

solution, reducing the time-to-market. The MAXM17572

employs peak-current-mode control architecture.

The MAXM17572 offers programmable switching frequency,

RESET output voltage monitoring, adjustable input

undervoltage lockout, and programmable soft-start. The

module also features hiccup-mode overload protection

and a thermal shutdown function.

The MAXM17572 is available in a low-profile, compact,

12-pin 3.5mm x 3.5mm x 2.3mm uSLIC package. Simulation

models are available.
