LTC1516 Overview
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 VIN and VOUT) make the LTC1516 ideally suited for small, light load battery-powered applications. Typical efficiency (VIN = 3V) exceeds 70%...
