Description
General part information
LP8867C-Q1 Series
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 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 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 support automotive stop, start and load dump condition. The LP886xC-Q1 integrates extensive fault detection features.
