Description
General part information
LTC1514 Series
The LTC1514-3.3/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 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 VINto VOUTdifferentials 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.ApplicationsBattery Operated EquipmentSmart Card ReadersLocal Power SuppliesHandheld InstrumentsBattery Backup Supplies
