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 compatible with diverse dimmers.

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 in SOIC-8 package. Features.
Primary Side Control for Output Current Regulation Without Opto-coupler and Secondary CV/CC Control Circuitry Adjustable Full Brightness and Full Dimming Setting Wide Dimming Range From 100% to 1%, Down to Full Darkness Adjustable Dimming Curve for.
