AAT3164 High Efficiency 1x/1.5x/2x Charge Pump

The AAT3164 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 is capable of driving up to six channels of LEDs at up to 30mA per channel f.
