LTC3221EDC-5#PBF

LINEAR TECHNOLOGY  LTC3221EDC-5#PBF  芯片, 电荷泵, 2.7-5.5V, 0.06A, 5V, 6DFN

The 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.
