General Description

The FC9921

from voltage sources ranging up to 400VDC. The FC9921

includes an internal high voltage switching MOSFET controlled

OFF) of approximately 10.5μs. The LED

string is driven at constant current, thus providing constant light

output and enhanced reliability. The output current is internally

provides good regulation of the output current throughout the

universal AC line voltage range of 85 to 265VAC or DC input

voltage of 20 to 400V.
