BP3337Eis a high PF PSR constant current LEDdriver with high current accuracy. lt is suitable for90Vac-277Vac universal input.
BP3337E achieve high PF by constant on timecontrol. With internal THD optimizer, the THD ofinput current can be further reduced. BP3337Eworks in BCM mode, which can help to improveswitching loss and EMC performance.
BP3337E adopts DlP-7 package.
