资 源 简 介

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 whiteLED 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 flyingcapacitors and two small bypass capacitors at VIN and OUT) makes these devices ideally suited for small, battery- powered applicaTIons.
