The Himalaya series of voltage regulator ICs, power modules, and chargers enable cooler, smaller, and simpler power supply solutions.
The MAXM17572 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.
