Data sheet:
The LP8872-Q1 is an automotive high-efficiency, low-EMI and easy-to-use LED driver with integrated DC-DC power switch. The DC-DC converter supports both boost and SEPIC topology configuration. The six high-precision current sinks support PWM phase shifting that is automatically adjusted based on the number of channels in use. LED brightness can be controlled globally through the I²C interface or PWM input.
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 boost voltage to the lowest sufficient level in all conditions.
The LP8872-Q1 supports built-in hybrid PWM dimming and analog current dimming, which reduces EMI, extends the LED lifetime, and increases the total optical efficiency.
