资 源 简 介
The LP5520 is an RGB backlight LED driver for small formatcolor LCDs. RGB backlight enables better colors on the displayand power savings compared with white LED backlight.LP5520 offers small and simple driver soluTIon without needfor opTIcal feedback. CalibraTIon in display module producTIoncan be done in one temperature. LP5520 produces true whitelight over wide temperature range. Three independent LEDdrivers have accurate programmable current sinks and PWMmodulation control. Using internal calibration memory andexternal temperature sensor, the RGB LED currents are adjustedfor perfect white balance independent of the brightnesssetting or temperature. The user programmable calibrationmemory has intensity vs. temperature data for each color.This white balance calibration data can be programmed to thememory on the production line of a backlight module.
