Description
General part information
LP8863-Q1 Series
The LP8863-Q1 is an automotive high-efficiency LED driver with boost controller. The six high-precision current sinks support phase shifting that is automatically adjusted based on the number of channels in use. Current sink brightness can be controlled individually and globally through the SPI or I2C interface; brightness can also be globally controlled with PWM input.
The boost controller has adaptive output voltage control based on the headroom voltages of the LED current sinks. This feature minimizes the power consumption by adjusting the voltage to the lowest sufficient level in all conditions. A wide-range adjustable frequency allows the LP8863-Q1 to avoid disturbance for AM radio band.
The LP8863-Q1 supports built-in hybrid PWM and current dimming, which reduces EMI, extends the LED lifetime, and increases the total optical efficiency.
