with PFC Function
SOIC8
CASE 751EB FL7701
Description MARKING DIAGRAM The FL7701 LED lamp driver is a simple IC with PFC function. The
special “adopted digital” technique of the IC can automatically detect
input voltage condition and send an internal reference signal for
achieving high power factor. When AC input is applied to the IC, PFC
function is automatically enabled. Otherwise, when DC input is
applied to the IC, PFC function is automatically disabled. The FL7701
does not need a bulk capacitor (electrolytic capacitor) for supply rail
stability, which can significantly affect to LED lamp system.
