MAX16931 Description

The MAX16930/MAX16931 offer two high-voltage, synchronous step-down controllers and a step-up preboost controller. They operate with an input voltage supply from 2V to 42V with preboost active and can “operate in drop-out condition by running at 95% duty cycle. The devices are intended for applications with mid- to high-power requirements that operate at a wide input voltage range such as during automotive coldcrank...
