AP1681 Datasheet | BCD Semiconductor

Preliminary Datasheet Off-line Primary Side Regulation Controller for Dimmable LED Driver AP1681 General Description 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 flicker and is patible with diverse dimmers. The AP1681 Features low start-up current, low operation current and high efficiency. It also has rich protection functions including over voltage, short circuit, over current and over temperature protections. The AP1681 is available...
