BP3182EB 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.
