19-4921; Rev 0; 3/10 www.DataSheet4U.com TION KIT EVALUA BLE IL AVA A WLED Charge Pump, RGB, OLED Boost, LDOs with ALC and CAI General Description The MAX8930 integrates a charge pump for white LED display backlighting with ambient light control (ALC) feature. The high-efficiency, adaptive-mode 1x/-0.5x charge pump drives up to 11 LEDs (8 WLEDs + RGB LED) with constant current for uniform brightness. The LED current is adjustable from 0.1mA to 25.6mA in 256 linear steps through I2C. High accuracy and LED-to-LED current matching are maintained throughout the adjustment range. The MAX8930 includes soft-start, thermal shutdown, open-circuit, and short-circuit protection. Three 200mA LDOs are provided with programmable output voltages to provide power to external circuitry.
