The AAT3369-1 is a low-noise, constant-frequency chargepump DC/DC converter that uses a dual-mode load switch(1x) and fractional (1.5x) conversion to maximize efficiencyfor white LED CABC (Content Adaptive BrightnessControl) applications. The AAT3369-1 is capable of driving6 white LEDs at a total 126mA in a wide input range. Thecurrent sinks may be operated individually or in parallelfor driving higher-current LEDs. A low external partscount (two 1μF flying capacitors and two small 1μF capacitorsat IN and OUTCP) makes the AAT3369-1 ideallysuited for small battery-powered applications.
