LP8543 Datasheet (Texas Instruments) - SMBus/I2C Controlled WLED Driver

LP8543, SMBus/I2C Controlled WLED Driver

The LP8543 is a white LED driver with integrated boost converter.

It has 7 adjustable current sinks which can be controlled by SMBus or I2C-compatible serial interface, PWM input and Ambient Light Sensor (ALS).

The boost converter has adaptive output voltage control based on the LED driver voltages.
