Overview

Description

The Himalaya series of voltage regulator ICs and power modules enable cooler, smaller, and simpler power-supply solutions. The MAXM15462/MAXM15463/MAXM15464 are a family of high-efficiency, synchronous step-down DC-DC modules with integrated controller, MOSFETs, compensation components, and inductor that operate over a wide input-voltage range. The modules operate from 4.5V to 42V input and deliver up to 300mA output current. The MAXM15463 and MAXM15464 are fixed 3.3V and 5V output modules respectively. The MAXM15462 is an adjustable output (0.9V to 5V) module. The modules significantly reduce design complexity, manufacturing risks, and offer a true plug and play power/ supply solution, reducing time-to-market.

The MAXM15462/3/4 modules employ peak-currentmode control architecture. To reduce input inrush current, the modules offer a fixed 4.1ms soft-start time.

The MAXM15462/3/4 modules are available in a low profile, compact 10-pin, 2.6mm × 3mm × 1.5mm, uSLIC™ package.
