AAT3369-1 Description
The AAT3369-1 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 CABC (Content Adaptive Brightness Control) applications. The AAT3369-1 is capable of driving 6 white LEDs at a total 126mA in a wide input range. The current sinks may be operated individually or in parallel for driving...
