General Description
The AAT3141 is a low noise, constant frequency charge pump DC/DC converter that uses a tri mode load switch (1X), fractional (1.5X), and doubling (2X) conversion to maximize efficiency for White LED applications. The device produces current levels up to 30mA on each of its 4 current source outputs to drive various arrangements of LEDs from a 2.7V to 5.5V input. Outputs may be operated individually or in parallel for driving higher-current LEDs. A low external parts count (two 1µF flying capacitors and two small 1µF capacitors at VIN, and CP) make the AAT3141 ideally suited for small battery-powered applications.
