晶丰明源半导体 High PF PSR LED Driver General Description BP3337DA is a high PF PSR constant current LED driver with high current accuracy. It is suitable for 90Vac-277Vac universal input. BP3337DA realizes high PF by constant on time control. With internal THD optimizer, the THD of input current can be further reduced. BP3337DA works in BCM mode, which can help to improve switching loss and EMC performance. BP3337DA adopts DIP-7 package.
