FEBFL7701-L30U003A: 85mA @ 28V(max), 90 ~ 265VAC

Summary

This document describes the proposed solution for a universal-input 2.4W LED ballast using the FL7701. The input voltage range is 90VRMS – 265VRMS and there is one DC output with a constant current of 85mA at 28VMAX. This document contains general description of FL7701, the power supply specification, schematic, bill of materials, and the typical operating characteristics.

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.
