BP3337DB is a low PF PSR (Primary Side Regulation)constant current LED driver with high current accuracyAlong with Boost pre-converter, BP3337DB canprovide two-stage isolated flicker-free light output.
BP3337DB provides with accurate constant on timecontrol and current limit to control primary sidecurrent in case of input voltage dip. So, transformsaturation is avoided to improve system reliability.
BP3337DB works in BCM mode, which can help toreduce switching loss and improve EMC performance
BP3337DB provides with multiple protections, suchas output over voltage protection (OVP), output shortcircuit protection (SCP), cycle-by-cycle over currentprotection(OVP)and thermal fold back.BP3337DBadopts DlP-7 package.
