MAXM15462

4.5V to 42V, 300mA Himalaya uSLIC Step-Down Power Module

Save Space and Reduce Heat, 300mA Synchronous Buck, Highly Efficient, Power Module in a New Micro-SLIC Package

Data Sheet

Please check latest availability status for a specific part variant.

Overview

Description

The Himalaya series of voltage regulator ICs and power modules enable cooler, smaller, and simpler power-supply solutions. The MAXM15462 is a high-efficiency, synchronous step-down DC-DC module with integrated controller, MOSFETs, compensation components, and inductor that operates over a wide input-voltage range. The module operates from 4.5V to 42V input and delivers up to 300mA output current over a programmable output voltage from 0.9V to 5V. The module significantly reduces design complexity, manufacturing risks, and offers a true plug and play power/supply solution, reducing time-to-market.

The MAXM15462 employs peak-current-mode control architecture. To reduce input inrush current, the device offers a fixed 4.1ms soft-start time.

The MAXM15462 module is available in a low profile, compact 10-pin, 2.6mm × 3mm × 1.5mm, uSLIC^™ package.
