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.
