DATA SHEET AAT1236 High Efficiency White LED Drivers for Backlight and Keypad General Description The AAT1236 is a highly integrated, high efficiency power solution for white LED and keypad backlights in mobile/ portable devices. It is based on a switching boost converter which steps up the single cell lithium-ion/polymer battery voltage to drive 5 strings of series-connected white LEDs with precision current regulation. The AAT1236 is capable of driving a total of four LEDs per channel. The boost converter can produce an output drive of up to 24V at 100mA. The high switching frequency (up to 2MHz) provides fast response to load transients and allows the use of small external components. A fully integrated control circuit simplifies the design and reduces total solution size.
