功能描述

The LTC®1516 is a micropower charge pump DC/DC converter that produces a regulated 5V output from a 2V to 5V supply. Extremely low supply current (12µA typical with no load, < 1µA in shutdown) and low external parts count (two 0.22µF flying capacitors and two 10µF capacitors at V IN and V OUT ) make the LTC1516 ideally suited for small, light load battery-powered applications. Typical efficiency (V IN = 3V) exceeds 70% with load currents between 50µA and 50mA. Modulating the SHDN pin keeps the typical efficiency above 70% with load currents all the way down to 10µA.The LTC1516 operates as either a doubler or a tripler depending on V IN and output load conditions to improve overall efficiency. The part has thermal shutdown and can survive a continuous short from V OUT to GND. In shut-down the load is disconnected from V IN .The LTC1516 is available in an 8-pin SO package in both commercial and industrial temperature grades.
