AP1681 Datasheet - BCD Semiconductor

AP1681 Off-line Primary Side Regulation Controller

The AP1681 is a powerful high performance AC/DC power supply controller for dimmable LED lighting applications. The device uses Pulse Frequency Modulation (PFM) technology to regulate output current according to the wall dimmer conduct angle. The AP1681 achieves wide dimming range without visible fl.

AP1681 Features
