The LPQ3336 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. LED brightness can be controlled globally through the I2C interface or PWM input.
The boost controller integrates an adaptive boost output voltage control based on the headroom voltages of the LED current sinks. This feature minimizes power consumption by adjusting the boost voltage to the lowest sufficient level in all conditions. A wide-range adjustable frequency allows the LPQ3336 to avoid disturbance for AM radio band.
The LPQ3336 device supports built-in hybrid PWM dimming and analog current dimming, which reduces EMI, extends the LED lifetime, and increases the total optical efficiency.
