The LP8867C-Q1, LP8869C-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 modeoperation. The device has four or three high-precision current sinks that can be combined forhigher current capability.
The DC-DC converter has adaptive output voltage control based on the LED forwardvoltages. This feature minimizes the power consumption by adjusting the voltage to the lowestsufficient level in all conditions. For EMI reduction DC-DC supports spread spectrum for switchingfrequency and an external synchronization with dedicated pin. A wide-range adjustable frequencyallows the LP886xC-Q1 to avoid disturbance for sensitive frequency band.
The input voltage range for the LP886xC-Q1 is from 4.5 V to 40 V to supportautomotive stop, start and load dump condition. The LP886xC-Q1 integrates extensivefault detection features.
