The Himalaya series of voltage regulator ICs and power modules enable cooler, smaller, and simpler power supply solutions. The MAXM17502 is a high-voltage, step-down power module in a family of pin-to-pin compatible modules with built-in thermally efficient system-in-packages (SiPs). The device includes a switch mode power supply controller, MOSFETs, an inductor, as well as the compensation components. The device operates from a 4.5V to 60V input supply voltage and supports adjustable output voltage from 0.9V to 5.0V with an output current of 1A. The high level of integration significantly reduces design complexity, manufacturing risks, and offers a true plug-and-play power supply solution to reduce time to market.

The pin-to-pin compatibility within this family of modules allows design flexibility as the design requirements change. For sequencing purpose, the device features adjustable soft-start time, programmable EN/UVLO threshold, and a power-good indicator (Active-Low RESET pin).

The MAXM17502 is available in a thermally enhanced, compact, 28-pin, 6.5mm x 10mm x 2.8mm SiP package. It operates over the -40°C to +125°C industrial temperature range.
