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.
