The LP8860-Q1 is an automotive high-efficiency LED driver with boost controller. It has 4 high-precision current sinks that can be controlled by a PWM input signal, an SPI or I2C master, or both.

The boost converter 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 LP8860-Q1 to avoid disturbance for AM radio band.

The LP8860-Q1 supports built-in hybrid PWM and current dimming, which reduces EMI, extends the LED lifetime, and increases the total optical efficiency. Phase-shift PWM reduces audible noise and output ripple.
