LTC3203BEDD Datasheet

PMIC - Voltage Regulators - DC DC Switching Regulators


The LTC3203BEDD /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 VIN and VOUT) make the LTC3203 family ideally suited for small, battery-powered applications. LTC3203BEDD Features &bull; Selectable Dual Mode Operation: 1:1.5 or 1:2&bull; High Output Current: Up to 500mA&bull; Low Noise Constant Frequency (1MHz/0.9MHz) Operation*&bull; VIN Range: 2.7V to 5.5V&bull; Adjustable Output Voltage (LTC3203/LTC3203B)&bull; User Selectable Fixed Output Voltages: 4.5V or 5V (LTC3203-1 and LTC3203B-1)&bull; Burst Mode&reg; Operation with IQ ~ 120&mu;A (LTC3203/LTC3203-1)&bull; Constant Freqency Operation at All Loads (LTC3203B/LTC3203B-1)&bull; Soft-Start Limits Inrush Current at Turn-On&bull; Short-Circuit/Thermal Protection&bull; Shutdown Disconnects Load from Input&bull; Shutdown Current: < 1&mu;A&bull; Available in a 10-pin (3mm &times; 3mm) DFN Package LTC3203BEDD Applications &bull; High Current LED Backlight Supply for&bull; Cellphones/PDAs Cellphone Camera Light Supply&bull; General Purpose 3.3V or Li-Ion to 5V Supply&bull; USB ON THE GO(OTG) Devices
