BP2329A Non-isolated Buck APFC Offline LED Controller Description The BP2329A is a high precision non-isolated buck controller with active PFC, specially designed for universal input offline constant current LED lighting.
The controller with on-chip PFC circuit achieves high power factor and low THD.
Operating in critical conduction mode, the power MOSFET switching loss is reduced and the inductor is fully utilized.
The BP2329A utilizes patent pending floating ground structure.
The inductor current is sensed during the whole switching cycle.
So it achieves high precision output current control, and excellent line regulation and load regulation.
The BP2329A offers rich protection functions t...
