The LP8867-Q1, LP8869-Q1 is an automotive highly-integrated, low-EMI,
easy-to-use LED driver with DC-DC converter. The DC-DC converter supports both boost and SEPIC mode
operation. The device has four or three high-precision current sinks that can be combined for
higher current capability.
The DC-DC converter has adaptive output voltage control based on the LED forward
voltages. This feature minimizes the power consumption by adjusting the voltage to the lowest
sufficient level in all conditions. For EMI reduction DC-DC supports spread spectrum for switching
frequency and an external synchronization with dedicated pin. A wide-range adjustable frequency
allows the LP886x-Q1 to avoid disturbance for sensitive frequency band.
The input voltage range for the LP886x-Q1 is from 4.5 V to 40 V to support
automotive start-stop and load dump condition. The LP886x-Q1 integrates extensive
fault detection features.
