BP2329AJ

Sample application

Sketch

The BP2329AJ is a high precision non-isolated buckcontroller with active PFC, specially designed foruniversal input offline constant current LED lighting.The controller with on-chip FC circuit achieves highpower factor and low THD. Operating in criticalconduction mode, the power MOSFET switching lossis reduced and the inductor is fully utilized
