LTC3624-2 Description

The LTC3624-2 is a high efficiency 17V, 2A synchronous monolithic step-down regulator. The switching frequency is fixed to 2.25MHz (LTC3624-2) with a ±40% synchronization range. The regulator features ultralow quiescent current and high efficiency over a wide VOUT range.

The step-down regulator operates from an input voltage range of 2.7V to 17V and provides an adjustable output range from 0.6V to VIN while delivering up to 2A 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 voltage ripple. The MODE pin can also be used to sync the switching frequency to an external clock.
