General Description
The AAT3131 is a low noise, constant frequency charge pump DC/DC converter that uses a dual mode Load Switch (1X) and fractional (1.5X) conversion to maximize efficiency for White LED applications. The device can be used to produce current levels up to 20mA in three of its outputs, and 30mA in one of its outputs to drive LEDs from a 2.7V to 5.5V input. Outputs may be operated individually or paralleled for driving higher-current LEDs. Low external parts counts (two 1μF flying capacitors and two small 1μF capacitors at VIN, and OUT) make the AAT3131 ideally suited for small battery-powered applications.
