LTC1522 Datasheet Micropower/ Regulated 5v Charge Pump DC/dc Converter

Manufacturer: Linear Technology (now Analog Devices)

Overview: LTC1522 Micropower, Regulated 5V Charge Pump DC/DC Converter.

General Description

The LTC®1522 is a micropower charge pump DC/DC converter that produces a regulated 5V output from a 2.7V to 5V input supply.

Extremely low supply current (6µA typical with no load, < 1µA in shutdown) and low external parts count (one 0.22µF flying capacitor and two 10µF capacitors at VIN and VOUT) make the LTC1522 ideally suited for small, light load battery-powered applications.

Typical efficiency (VIN = 3V) exceeds 75% with load currents between 50µA and 20mA.
