Overview
iW3609 AC/DC Digital Power Controller for Single-Stage High Power Factor Dimmable LED Drivers 1 Description The iW3609 is a single-stage, high-performance AC/DC offline power supply controller for dimmable LED luminaires.
It applies advanced digital control technology to detect the dimmer type, which provides dynamic impedance to interface with the dimmer and control the LED brightness at the same time.
With advanced dimmer detection technology, the iW3609 can operate with most wall dimmers including leading-edge dimmers (R-type or R-L type) and trailing-edge dimmers (R-C type).
In addition, the iW3609’s cycle-by-cycle waveform analysis technology allows for fast dimmer setting response.
When no dimmer is on the line, the iW3609 optimizes the power factor and minimizes the current harmonic distortion to the AC line.
Furthermore, in no dimmer condition, output current is regulated at nominal output current value over a wide input voltage range.
The iW3609 operates the main power c...
