LP8862-Q1 2-Channel LED Driver Texas Instruments LP8862-Q1 2-Channel LED Driver is an automotive high-efficiency, low-EMI, easy-to-use LED driver with an integrated DC-DC converter. The DC-DC supports both boost and SEPIC modes of operation. The device has two high-precision current sinks that can provide high dimming ratio brightness control with a PWM input signal. The DC-DC converter has an adaptive output voltage control based on the LED current sink headroom voltages. This feature minimizes power consumption by adjusting the voltage to the lowest sufficient level in all conditions. DC-DC supports spread spectrum for switching frequency and an external synchronization with a dedicated pin. The high switching frequency allows the LP8862-Q1 to avoid disturbance for AM radio band.
