iW3623 AC/DC Digital Power Controller for High Power Factor Dimmable LED Drivers 1 Description The iW3623 is a high-performance AC/DC off-line power supply controller for LED luminaires. The iW3623 combines power factor correction and LED current regulation into one controller. It achieves PF > 0.95 and THD < 10% for 100–277VAC input voltage range. The iW3623 operates in quasi-resonant mode to provide high efficiency. The device uses Dialog’s advanced PrimAccurate™ primary-side sensing technology to achieve excellent line and load regulation without a secondary-feedback circuit. In addition, the iW3623’s pulse-by-pulse waveform analysis technology allows accurate LED current regulation.
