Description

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.
