AP1681 - Off-line Primary Side Regulation Controller

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.

Key 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 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.
