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.
