AP1682 Datasheet | BCD Semiconductor

Data Sheet Single Stage Primary Side Regulation PFC Controller For LED Driver AP1682 General Description The AP1682 is a high performance AC/DC universal input Primary Side Regulation Power Factor Controller for LED driver applications. The device uses Pulse Frequency Modulation (PFM) technology to regulate output current while achieving high power factor and low THD. The AP1682 provides accurate constant current (CC) regulation while removing the opto-coupler and secondary control circuitry. It also eliminates the need of loop pensation circuitry while maintaining stability. The AP1682 achieves excellent regulation and high efficiency, yet meets the requirement of IEC61000-3-2...
