The AAT3103 is a constant frequency charge-pump based current-source white LED driver capable of driving one to three LEDs up to 30mA, each. The charge pumps automatically
switch between 1x mode and 2x mode to maintain the highest efficiency and optimal LED current accuracy and matching. A low external parts count (one 1μF flying capacitor, two small 1μF capacitors at IN and OUT and one current setting resistor) makes the AAT3103 ideally suited for small battery-powered applications.
