BP3316D

BP3316D PSR Single-Stage APFC Offline LED Driver Description The BP3316D is a high precision primary-side regulation driver with single stage Active PFC, specially designed for universal input offline flyback or buck-boost constant current LED lighting. The driver 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 BP3316D adopts proprietary primary side current sensing scheme. It can precisely control the LED current without secondary side sense and feedback circuits. The device integrates a 650V power MOSFET to further reduce external components, for saving cost and PCB area. The BP3316D utilizes patented line and load voltage compensation method to achieve excellent line and load regulation. The BP3316D offers rich protection functions to improve the system reliability, including LED open circuit protection, LED short circuit protection, VCC over voltage protection, VCC under voltage protection, CS resistor open 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 driver is over temperature. Typical Application Features  Single-Stage Active PFC for High Power Factor and Low THD  Primary Side Control Constant Current Operation, No Opto-Coupler required  Integrated 650V Power MOSFET...
