RGB backlights enable better Color colors on the display and power savings compared • Individual Calibration Coefficients for Each Color with white LED backlights. The device offers a small • Color AccuracyΔX andΔY≤ 0.003 and simple driver solution without need for optical feedback. Calibration in display module production • 12-Bit ADC for Measurement of 2 Sensors can be done in one temperature. The LP5520 • Adjustable Current Outputs for Red, Green, and produces true white light over a wide temperature Blue (RGB) LED range. Three independent LED drivers have accurate • 0.2% Typical LED Output Current Matching programmable current sinks and PWM modulation control. Using internal calibration memory and • PWM Control Inputs for Each Color external temperature sensor, the RGB LED currents 2 • SPI™ and I C-Compatible Interface are adjusted for perfect white balance independent of • Stand-Alone Mode With One-Wire Control the brightness setting or temperature. The user programmable calibration memory has intensity vs • Sequential Mode for One Color at a Time temperature data for each color. This white balance • Magnetic High Efficiency Boost Converter calibration data can be programmed to the memory • Programmable Output Voltage from 5 V to 20 V on the production line of a backlight module. • Adaptive Output Voltage Control Option The device has a magnetic boost converter that • < 2-µA Typical Shutdown Current creates a supply voltage of up to 20 V LED from the battery voltage. The output can be set at 1-V steps 2 Applications from 5 V to 20 V. In adaptive mode the circuit automatically adjusts the output voltage to minimum • Color LCD Display Backlighting sufficient level for lowest power consumption. • LED Lighting Applications Temperature is measured using an external temperature sensor placed close to the LEDs. The second ADC input can be used, for example, for ambient light measurement.
