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.
