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 to
improve the system reliability, including LED open
circuit protection, LED short circuit protection, VCC
under voltage protection, CS resistor open circuit
protection and cycle by cycle current limit. All the
protection functions are auto-recovery. The system
reliability is further improved by the thermal
regulation function. The output current is reduced
when the controller is over temperature.
