AAT2856 | High Current Charge Pump With Dual LDO For Backlight Applications

The AAT2856 is a highly integrated Charge Pump with dual linear Regulators optimized for systems powered from lithium-ion/polymer batteries. The Charge Pump provides power for white LED backlight. Six backlight LEDs CAN be driven at up to 30mA. AnalogicTech's AS2Cwire (Advanced Simple Serial Control) single-wire Interface is used to enable, disable, and set the current to one of 32 levels for the backlight. Backlight current matching is 1% for uniform Display brightness. The AAT2856 offers two high-performance low-noise MicroPower low dropout (LDO) linear Regulators Both Regulators use individual enable inputs and each will supply up to 200mA load current. LDO ground pin current is only 80A, making the AAT2856 ideal for battery-operated applications. The AAT2856 is equipped with built-in short-circuit and over-temperature protection. The soft start circuitry prevents excessive inrush current at start-up and mode transitions. The AAT2856 is available in a Pb-free TQFN44-28 package and operates over the -40C to +85C ambient temperature range.
