The FL7701MX is a smart non-isolated Buck LED Driver 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 LED lamp driver is a simple IC does not need a bulk capacitor (electrolytic capacitor) for supply rail stability, which can significantly affect LED lamp system lifetime.
