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.
The BP3315 utilizes patented line and load
voltage compensation method to achieve excellent line and load regulation.
The BP3315 offers rich protection functions to improve the system reliability, including LED open circuit protection, LED short circuit protection, VCC over
voltage...
