BP3337DB Description
BP3337DB is a low PF PSR (Primary Side Regulation) constant current LED driver with high current accuracy. Along with Boost pre-converter, BP3337DB can provide two-stage isolated flicker-free light output. BP3337DB provides with accurate constant on time control and current limit to control primary side current in case of input voltage dip.
