Linear Technology LTC1516

the LTC1516 ideally suited for small, light load battery-powered applications. The LTC1516 operates as either a doubler or a tripler depending on VIN and output load conditions to improve overall efficiency. The part has thermal shutdown and can survive a continuous short from VOUT to GND.

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 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. In shutdown the load is disconnected from VIN. The LTC1516 is available in an 8-pin SO package in both commercial and industrial temperature grades. , LTC and LT are registered trademarks of Linear Technology Corporation. s s s s Ultralow Power: Typical Operating ICC = 12µA Short Circuit/Thermal Protection Regulated 5V ± 4% Output 2V to 5V Input Range No Inductors ICC in Shutdown: < 1µA Output Current: 20mA (VIN > 2V) 50mA (VIN > 3V) Shutdown Disconnects Load from VIN In...
