LP5520 - RGB Backlight LED Driver

Description

The LP5520 is an RGB backlight LED driver for small format color LCDs.

RGB backlight enables better colors on the display and power savings compared with white LED backlight.

LP5520 offers small and simple driver solution without need for optical feedback.

Features

  • Temperature compensated LED intensity and color Individual calibration coefficients for each color Color accuracy ΔX and ΔY ≤ 0.003 12 bit ADC for measurement of 2 sensors Adjustable current outputs for R, G and B LED 0.2% typical LED output current matching PWM control inputs for each color SPI and I2C compatible interface Stand-alone mode with 1 wire control Sequential mode for one color at a time Magneti.

www.DataSheet4U.com May 2007 LP5520 RGB Backlight LED Driver LP5520 RGB Backlight LED Driver General Description The LP5520 is an RGB backlight LED driver for small format color LCDs. RGB backlight enables better colors on the display and power savings compared with white LED backlight. LP5520 offers small and simple driver solution without need for optical feedback. Calibration in display module production can be done in one temperature. LP5520 produces true white light over wide temperature range. Three independent LED drivers have accurate programmable current sinks and PWM modulation control. Using internal calibration memory and external temperature sensor, the RGB LED currents are adjusted for perfect white balance independent of the brightness setting or temperature.
