iW3623 Datasheet (iWatt) - AC/DC Digital Power Controller

iW3623, AC/DC Digital Power Controller

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-resona
