Product Overview

The LTC3621EDCB-2#TRMPBF is a high-efficiency synchronous monolithic Step-down Regulator for use with portable-handheld scanners. The switching frequency is fixed to 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 2.7 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 tradeoff 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.
  • Full dropout operation with low IQ
  • Current-mode operation for excellent line and load transient response
  • Synchronizable to external clock
  • Internal compensation and soft-start
  • Over-temperature protection
  • 95% Maximum efficiency
  • <3.5µA Low quiescent current in zero-current shutdown
  • ±1% Output voltage accuracy
