Off-line Primary Side Regulation Controller for Dimmable LED Driver

AP1681

Features

General Description

•

Primary Side Control for Output Current

Regulation Without Opto-coupler and Secondary

CV/CC Control Circuitry

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.

•

Adjustable Full Brightness and Full Dimming

Setting

Wide Dimming Range From 100% to 1%, Down

to Full Darkness

Adjustable Dimming Curve for Human Eye

Sensitivity

No Visible Flicker

Connectivity with Analog / Digital / Hybrid

Dimming Mode

Built-in Acceleration Start

Adjustable Soft-start Timing

CV Open-load Regulation and Reload Detection

Over Voltage and Short Circuit Protection

Over Temperature Protection

Over Current Protection

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 in SOIC-8 package.
