Lighting Management System For Six White LEDs And One RGB Or FLASH LED

LP3936 is a complete lighting management system designed for portable Wireless applications. It contains a boost DC/DC converter, 4 White LED Drivers to drive the main LCD panel backlight, 2 White LED Drivers for sub-LCD panel and 1 set of RGB LED Drivers
Both WLED groups have 8-bit programmable constant current drivers that are separately adjustable and matched to 1% (typ.). For efficient backlighting the backlight intensity CAN be adjusted using the 8-bit ADC with ambient light detection circuit.
The RGB LED Drivers are PWM-driven with programmable color, intensity and blinking patterns. In addition, they feature a Flash function to support picture taking with camera-enabled cellular phones.
An efficient magnetic boost converter provides the required bias operating from a single Li-Ion battery. The DC/DC converter output voltage is user programmable for adapting to different LED types and for efficiency optimization. All functions are software controllable through an I2C and MicroWire/SPI compatible Interface and 16 internal Registers
