General Description

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 from a 2.7V to 5.5V input.

The current sinks may be operated individually or in parallel for driving higher-current LEDs.
