BP2872XD

Sample application

Sketch

BP2872GD is a constant current driver chip specifically designed for low PF floating ground Buck LED. It adopts full-cycle closed-loop sampling, which improves the constant current accuracy over a wide output range. BP2872GD can achieve the function of current adjustment by DIP switch through an independent CS current signal sampling pin.

Advantage

Full-cycle sampling of inductor current, with high constant current accuracy.
Excellent load regulation rate
Support ultra-wide output voltage load
External NTC over-temperature current reduction
Built-in 500V MOSFET
High-precision current reference (+/- 3%)
