Available in a 10-pin (3mm × 3mm) DFN Package
The LTC ? 3203/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 V IN and V OUT ) make the LTC3203
family ideally suited for small, battery-powered applica-
tions.
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
