LP8556 Datasheet (Texas Instruments) - High-Efficiency LED Backlight Driver

LP8556, High-Efficiency LED Backlight Driver

The LP8556 device is a white-LED driver featuring an asynchronous boost converter and six high precision current sinks that can be controlled by a PWM signal or an I2C master.

The boost converter uses adaptive output voltage control for setting the optimal LED driver voltages as low as 7 V and as hi
