Description

General part information

LTC1515 Series

The LTC1515, LTC1515-3/5 and LTC1515-3.3/5 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 adjustable using an external resistor divider (LTC1515) or programmable to either 3V/5V (LTC1515-3/5) or 3.3V/5V (LTC1515-3.3/5) using a logic pin.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 power-on reset circuit forces the POR pin low on initial power-up. The POR output remains low until 200ms (typ) after VOUTis in regulation.The parts are short-circuit and over-temperature protected. Battery life is maximized by very low operating currents (ICC= 60µA typ, ICC<1µA in shutdown). All three parts are available in an SO-8 package.ApplicationsSIM Interface in GSM Cellular TelephonesSmart Card ReadersLocal Power SuppliesPortable Equipment
