The LTC
The LTC3624/LTC3624-2 is a high efficiency 17V, 2A synchronous monolithic step-down regulator. The switching frequency is fixed to 1MHz (LTC3624) or 2.25MHz (LTC3624-2) with a +40% synchronization range. It features ultralow quiescent current and high efficiency over a wide VOUT range.
The 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 allows trading off ripple noise for light load efficiency via Burst Mode, Pulse-Skipping, or Forced Continuous operation.
