The BP3167XHis a high precision primary-sidefeedback and regulation controller for LED lighting, itoperates in constant current control mode and isdesigned to work in inductor current discontinuousconduction mode and especially suitable for flybackconvertor under universal input.
The BP3167XH integrates a 600V/650V power MOSFET,with gate MOSFET driving technique.lt doesn’t needthe auxiliary winding for vcc supply. lt can achieveexcellent constant current performance with very fewexternal components, so the system cost and size areminimized.
The BP3167XH offers rich protections to improve thereliability, including LED short circuitsystemprotection, LED open protection, thermal regulationfunction.
