Product Overview

The LTC3622EDE-2#PBF is a dual 1A output high efficiency synchronous monolithic Step-down Regulator capable of operating from input supplies up to 17V. The switching frequency is fixed to 2.25MHz with a ±50% synchronization range to an external clock. The regulator features ultralow quiescent current and high efficiency over a wide output voltage range. The step-down regulators operate from an input voltage range of 2.7 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 regulators can be synchronized to an external clock. Furthermore, fixed VOUT options are available to eliminate the external feedback resistors.
  • Up to 95% Efficiency
  • High efficiency, low dropout operation (100% duty cycle)
  • ±1% Output voltage accuracy
  • Current mode operation for excellent line and load transient response
  • Phase shift programmable with external clock
  • Selectable current limit
  • Internal compensation and soft-start
