BP3315 PSR Single-Stage APFC Offline LED Driver Description The BP3315 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 BP3315 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.
