iW3689 Datasheet AC/dc Digital Power Controller

Manufacturer: Dialog Semiconductor (now Renesas)

Overview: iW3689 AC/DC Digital Power Controller for Single-Stage High Power Factor Dimmable LED.

General Description

The iW3689 is a single-stage, high-performance AC/DC off-line power supply controller for dimmable LED luminaires.

It applies advanced digital control technology to detect the dimmer type, enabling it to provide dynamic impedance to interface with the dimmer and to control the LED brightness at the same time.

With advanced dimmer detection technology, the iW3689 can operate with most wall dimmers including leading-edge dimmers (R-type or R-L type), trailing-edge dimmers (R-C type), and smart dimmers.
