Product Overview

The LTC3221EDC-5#PBF is a micro-power DC/DC charge-pump Converter that produces a regulated output at up to 60mA. The input voltage range is 1.8 to 5.5V. Extremely low operating current and low external parts count makes it ideally suited for small, battery-powered applications. It includes fixed 5 and 3.3V output versions plus an adjustable version. This part operates as Burst Mode® switched capacitor voltage doubler to achieve ultralow quiescent current. The chips use a controlled current to supply the output and will survive a continuous short-circuit from VOUT to GND. The FB pin of the adjustable LTC3221 can be used to program the desired output voltage.
  • No inductors needed
  • Shutdown disconnects load from VIN
  • Burst mode control
  • Short-circuit protected
  • Up to 60mA output current
  • <1µA Very low shutdown current
  • <1mm Solution profile
