3 Description

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 widerange

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.
