LTC1522 - Micropower, Regulated 5V Charge Pump DC/DC Converter

The LTC1522 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 (6A typical with no load, <1A in shutdown) and low external parts count (one 0.22F flying capacitor and two 10F 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 50A and 20mA. Modulating the SHDN pin keeps the typical efficiency above 75% with load currents all the way down to 10A. The LTC1522 has thermal shutdown and CAN survive a continuous short from VOUT to GND. In shutdown the load is disconnected from VIN. The part is available in 8-pin MSOP and SO packages. The LTC1522 is pin compatible with the LTC1516 in applications where VIN >/= 2.7V and IOUT By Linear Technology Corporation
