AAT2806 Dual High Efficiency Charge Pump for White LED and Flash Applications General Description The AAT2806 is a dual charge pump designed to support both the white LED backlight and flash applications for systems operating with lithium-ion/polymer batteries.
The backlight charge pump is capable of driving up to four LEDs at a total of 80mA.
The current sinks may be operated individually or in parallel for driving higher current LEDs.
To maximize power efficiency, the charge pump operates in 1X, 1.
5X, or 2X mode, where the mode of operation is automatically selected by comparing the forward voltage of each LED with the input voltage.
