资 源 简 介

The AAT3121 is a low noise, constant frequencycharge pump DC/DC converter that uses fracTIonal(1.5X) conversion to increase efficiency in whiteLED applicaTIons. With input voltages ranging from2.7V to 5.5V, the device can produce an output currentof up to 120mA. A low external parts count (two1μF flying capacitors and two small bypass capacitorsat VIN and OUT) makes the AAT3121 ideallysuited for small battery-powered applicaTIons.
