iW3612  
AC/DC Digital Power Controller for  
Dimmable LED Drivers  
1.0 Features  
● Isolated AC/DC offline 100VAC /230VAC LED driver  
● Line frequency ranges from 45Hz to 66Hz  
● Intelligent wall dimmer detection  
2.0 Description  
The iW3612 is a high performance AC/DC offline power  
supply controller for dimmable LED luminaires, which uses  
advanced digital control technology to detect the dimmer  
type and phase. The dimmer conduction phase controls  
the LED brightness. The LED brightness is modulated by  
PWM-dimming. iW3612’s unique digital control technology  
eliminates visible flicker.

Trailing-edge dimmer  
No-dimmer detected  
Unsupported dimmer  
iW3612 can operate with all dimmer schemes including:  
leading-edge dimmer, trailing-edge dimmer, as well as  
other dimmer configurations such as R-type, R-C type or  
R-L type. When a dimmer is not present, the controller can  
automatically detect that there is no dimmer.  
● Hybrid dimming scheme  
● Wide dimming range from 1% up to 100%  
● Optimized for PF > 0.7  
iW3612 operates in quasi-resonant mode to provide  
high efficiency. The iW3612 provides a number of key  
built-in features. The iW3612 uses iWatt’s advanced primary-  
● No visible flicker  
● Resonant control to achieve high efficiency, 85% without side sensing technology to achieve excellent line and load  
dimmer  
regulation without secondary feedback circuitry. In addition,  
iW3612’s pulse-by-pulse waveform analysis technology  
allows accurate LED current regulation. The iW3612  
maintains stability over all operating conditions without the  
need for loop compensation components. Therefore, the  
iW3612 minimizes external component count, simplifies EMI  
design and lowers overall bill of materials cost.

3.0 Applications  
● Dimmable LED luminaires  
● Primary-side sensing eliminates the need for  
opto-isolator feedback and simplifies design  
● Tight LED current regulation ± 5%  
● Fast start-up, typically 10µA start-up current  
● Hot-plug LED module support  
● Optimized for 3W - 25W output power  
● Capable of higher output power with enhanced external  
driver
