Advanced Analogic Technologies AAT2842: Charge pump combines dual low-dropout regulators and serial interfaces

Targeting portable systems using lithium-ion/polymer batteries, the 600-mA AAT2842 charge pump combines dual low-dropout linear regulators and serial-digital interfaces, providing independent control of LED functions. Two S²Cwire (Simple Serial Control) serial-digital interfaces allow designers to independently drive four LEDs for backlight display or keypad applications and four LEDs for high-current flash applications. The AAT2842 costs $1.75 (1000).
