4V to 42V, 100mA, Compact Step-Down Power Module

MAXM17532

The MAXM17532 is a step-down DC-DC power module built in a compact uSLICTM package. The MAXM17532 integrates a controller, MOSFETs, an inductor, as well as the compensation components. The device operates from an input voltage of 4.0V to 42V, supports an adjustable output voltage from 0.9V to 5.5V, and supplies up to 100mA of load current. The high level of integration significantly reduces design complexity, manufacturing risks and offers a true “plug and play” power supply solution, hence reducing the time-to-market.
