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 PrimAccurateprimary-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. The iW3623 maintains stability
over all operating conditions without the need for loop compensation components.
