Description

General part information

LTC1522 Series

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 (6µA typical with no load, <1µA in shutdown) and low external parts count (one 0.22µF flying capacitor and two 10µF capacitors at VINand VOUT) make the LTC1522 ideally suited for small, light load battery-powered applications. Typical efficiency (VIN= 3V) exceeds 75% with load currents between 50µA and 20mA. Modulating the SHDN pin keeps the typical efficiency above 75% with load currents all the way down to 10µA.The LTC1522 has thermal shutdown and can survive a continuous short from VOUTto 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≤ 20mA.ApplicationsSIM Interface Supplies for GSM Cellular TelephonesLi-Ion Battery Backup SuppliesLocal 3V to 5V ConversionSmart Card ReadersPCMCIA Local 5V Supplies
