General Description

The AAT3153 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 AAT3153 is capable of driving sixchannel LEDs from a 2.7V to 5.5V input.

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