Description The BP3182EB is a PSR (Primary Side Regulation) constant current LED driver with high current accuracy used for low PF two-winding Flyback circuit. Along with Boost pre-converter, an application scenario of twostage isolated flicker-free light output is available. The BP3182EB detects output voltage and demagnetization signal without auxiliary winding, while keeping excellent OVP accuracy. The BP3182EB adopts advanced PSR technology without secondary side feedback circuit and loop compensation capacitor to provide excellent constant output current regulation with extreme low system cost and tiny size. Integrated with internal MOSFET, system cost is further reduced and easy for PCB layout.
