High Efficiency 1.5X Fractional Charge Pumps For White LED Applications General Description The AAT3113 and AAT3114/14A are low noise, constant frequency charge pump DC/DC converters that use fractional (1.5X) conversion to increase efficiency in white LED applications. The devices can be used to produce current levels up to 20mA for each output from a 2.7V to 5.5V input. A low external parts count (two 1µF flying capacitors and two small bypass capacitors at VIN and OUT) makes these devices ideally suited for small, battery-powered applications.
