Description

The LTC®1514-3.3/LTC1514-5 are micropower switched capacitor DC/DC converters that produce a regulated output voltage by either stepping up or stepping down the input voltage. Output voltage is fixed at either 3.3V (LTC1514-3.3) or 5V (LTC1514-5) by an internal resistor divider. 

A unique architecture of LTC1514-3.3/LTC1514-5 allows the parts to accommodate a wide input voltage range (2V to 10V) while maintaining ±4% regulation. Additional circuitry prevents excessive inrush current and output voltage ripple when large VIN to VOUT differentials are present. 

An internal uncommitted comparator of LTC1514-3.3/LTC1514-5 is kept active in shutdown. The comparator has an open-drain output for flexible interfacing. The parts are short-circuit and overtemperature protected. Battery life is maximized by very low operating currents (ICC = 60mA typ, 10mA in shutdown). Both parts are available in an SO-8 package.
