Product Overview

LTC®3622 is a dual 1A output, high efficiency synchronous monolithic step-down regulator capable of operating from input supplies up to 17V. The regulator features ultralow quiescent current and high efficiency over a wide output voltage range. The step-down regulator operate from an input voltage range of 2.7V to 17V and provide an adjustable output from 0.6V to VIN while delivering up to 1A of output current. A user-selectable mode input is provided to allow the user to trade off ripple noise for light load efficiency. Burst Mode® operation provides the highest efficiency at light loads, while pulse-skipping mode provides the lowest ripple noise. The switching regulator can be synchronized to an external clock. Typical applications are battery powered systems, point-of-load supplies, portable – handheld scanners.
