Description

General part information

LTC3203LTC3203-1LTC3203BLTC3203B-1 Series

The LTC3203/LTC3203-1/LTC3203B/LTC3203B-1 are low noise, high efficiency charge pump DC/DC converters capable of driving loads up to 500mA from a 2.7V to 5.5V input. Low external parts count (two flying capacitors and bypass capacitors at VINand VOUT) make the LTC3203 family ideally suited for small, battery-powered applications.Built-in soft-start circuitry prevents excessive inrush current during start-up. High switching frequency enables the use of small external capacitors. The LTC3203/LTC3203-1 feature Burst Mode operation at light load to achieve high efficiency whereas the LTC3203B/LTC3203B-1 operate at constant frequency to achieve lowest noise operation.The LTC3203-1/LTC3203B-1 have a user selectable fixed output voltage of 4.5V or 5V to power LEDs or logic circuits. The FB pin of the LTC3203/LTC3203B can be used to program the desired output voltage. The parts are short-circuit and over temperature protected and are available in a low profile (3mm × 3mm) DFN package.ApplicationsHigh Current LED Backlight Supply for Cellphones/PDAsCellphone Camera Light SupplyGeneral Purpose 3.3V or Li-Ion to 5V SupplyUSB ON THE GO(OTG) Devices
