LTC1516 Micropower, Regulated 5V Charge Pump DC/DC Converter FEATURES s s s s s s s DESCRIPTION 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% 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 VIN and output load conditions to improve overall efficiency.
