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.
