2 / 15 page June 2013 © 2011 Fairchild Semiconductor Corporation www.fairchildsemi.com FL7701 • Rev. 1.0.4 FL7701 Smart LED Lamp Driver IC with PFC Function Features Digitally Implemented Active PFC Function (No Additional Circuit Necessary for High PF) Built-in HV Supplying Circuit: Self Biasing Application Input Range: 80 V AC ~ 308 VAC AOCP Function with Auto-Restart Mode Built-in Over-Temperature Protection Function Cycle-by-Cycle Current Limit Current-Sense Pin Open Protection Low Operating Current: 0.85 mA (Typical) Under-Voltage Lockout with 5 V Hysteresis Programmable Oscillation Frequency Programmable LED Current Analog Dimming Function Soft-Start Function Precise Internal Reference: ±3% Applications LED Lamp for Decorative Lighting LED Lamp for Low-Power Lighting 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.
