The iW3623 is a high-performance AC/DC off-line power supply controller for LED luminaires.

The iW3623 bines power factor correction and LED current regulation into one controller.

It achieves PF > 0.95 and THD < 10% for 100– 277VAC input voltage range.

Isolated AC/DC off-line LED driver.
Power factor > 0.95 for wide input voltage range 100.
277VAC.
Total harmonic distortion (THD) < 10%.
Under 5% 100Hz/120Hz output current ripple.
Resonant control to achieve high efficiency.
LED current foldback with external NTC.
Small size design xx Small size input bulk capacitor xx Small size output capacitor xx Small transformer.
Primary-side sensing eliminates the ne.
