DESCRIPTION KEY FEATURES White LED Backlight Controller for Middle Size Display Panels Up to 6 LED Strings with 0.5% Precision Current Matching Wide Input Voltage Range from 6V to 28V Temperature Compensated LED Current Ultrasonic Pulse Skipping for audible noise reduction Direct Ambient Light Sensor Interface for Brightness Control High Efficiency over Full Dimming Range Low Standby Current On-chip Thermal Shut-down Over-voltage Protection Packaged in a Thermally Efficient 24 pin 4x4mm MLPQ Package APPLICATIONS LX1996 is an integrated white LED driver for notebook size displays. It is designed to drive up to six strings of LEDs. The LX1996 consists of a boost converter includes a direct analog light sensor interface and can be dimmed by a PWM signal or by application of a DC control voltage. Precision current mirror circuitry sets all channels to the same current with a single programming input. The current value can be programmed up to 30mA per channel with a single resistor from the FEATURES White LED Backlight Controller for Middle Size Display Panels Up to 6 LED Strings with 0.5% Precision Current Matching Wide Input Voltage Range from 6V to 28V Temperature Compensated LED Current Ultrasonic Pulse Skipping for audible noise reduction Direct Ambient Light Sensor Interface for Brightness Control High Efficiency over Full Dimming Range Low Standby Current On-chip Thermal Shut-down Over-voltage Protection Packaged in a Thermally Efficient 24 pin 4x4mm MLPQ Package APPLICATIONS LX1996 is an integrated white LED driver for notebook size displays.
