BP2876D
BP2876D
PWM Dimmable Buck LED Driver
Description
BP2876D is a high-precision, buck mode and
constant current LED driver IC which supports
PWM dimming, it combines analog dimming mode
and PWM dimming mode, meanwhile it could
optimize linear of dimming and consistency of
luminous flux. BP2876D could be used in the non-
isolated buck mode constant current LED
power which is suitable for 85Vac~265Vac voltage
range, it is designed for flicker- free lightning field
on purpose.
BP2876D integrates a 500V power MOSFET. It
utilizes patent pending MOSFET driving technique
and current sensing method. The operating
current of the IC is very low. With very few external
components count and no auxiliary winding., it can
achieve excellent constant current performance,
so the system cost and size are greatly reduced.
There is high-precision current sense circuit inside
the BP2876D, meanwhile the IC uses the
patented constant current control, which achieves
high-precision constant current output and great
line voltage regulation. The IC works under inductor
current critical conduction mode, so the output
current is invariant with the inductance and LED
voltage and it can achieve excellent load
regulation.
BP2876D has various protections, includes LED
open circuit protection, LED short circuit protection,
CS resistor short circuit protection, input under-
voltage protection, over temperature regulation
and thermal fold back.
BP2876D uses the SOP7 package.
