Introduction
The LTC3621/LTC3621 - 2 is a high efficiency 17V, 1A synchronous monolithic step - down regulator. The switching frequency is fixed to 1MHz or 2.25MHz with a ±40% synchronizing range. The regulator features ultralow quiescent current and high efficiencies 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 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 voltage ripple. The MODE pin can also be used to allow the user to sync the switching frequency to an external clock.
Features
- Wide VIN Range: 2.7V to 17V
- Wide VOUT Range: 0.6V to VIN
- 95% Max Efficiency
- Low 3.5µA Quiescent Current, Zero - Current Shutdown
