General 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 cold-crank or engine stop-start conditions.
