LP8864-Q1 High-Efficiency LED Driver
Texas Instruments LP8864-Q1 High-Efficiency LED Driver comes with a boost controller. The four high-precision current sinks support phase shifting that is automatically adjusted based on the number of channels used. 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 power consumption by adjusting the boost voltage to the lowest sufficient level in all conditions. A wide-range adjustable frequency allows the LP8864-Q1 to avoid disturbance from the AM radio band. The Texas Instruments LP8864-Q1 supports built-in hybrid PWM dimming and analog current dimming, which reduces EMI, extends the LED lifetime, and increases the total optical efficiency.
