General Description

The FC9922

from voltage sources ranging up to 400VDC. The FC9922

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

50mA for FC9922. The peak current control scheme 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.
