Overview
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.
