General Description

The AAT3123/23A/24 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 to drive up to six LEDs from a 2.7V to 5.5V input.

Outputs may be operated individually or paralleled for driving higher-current LEDs.
