♠ LP8866S-Q1 Automotive Display LED-backlight Driver with Six 150-mA Channels
The LP8866S-Q1 is an automotive high-efficiency LED driver with boost controller. The Six highprecision current sinks support 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 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 boost voltage to the lowest sufficient level in all conditions. A wide-range adjustable frequency allows the LP8866S-Q1 to avoid disturbance for AM radio band.
The LP8866S-Q1 supports built-in hybrid PWM dimming and analog current dimming, which reduces EMI, extends the LED lifetime, and increases the total optical efficiency.
