Linear Technology LTC1514-3.3

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.

DESCRIPTION

Output voltage is fixed at either 3.3V (LTC1514-3.3) or 5V (LTC1514-5) by an internal resistor divider. A unique architecture 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 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 = 60µA typ, 10µA in shutdown). Both parts are available in an SO-8 package. , LTC and LT are registered trademarks of Linear Technology Corporation. 3.3V or 5V Output Voltages 2V to 10V Input Voltage Range Up to 50mA Output Current Only Three External Capacitors Required Soft Start Limits Inrush Current at Turn-On Low Operating Current: 60µ...
