DESCRIPTION
IL9921, IL9922, IL9923 are high-voltage LED driver control ICs with build-in MOSFET switch
and purposed for LED lighting control.
They allow efficient operation of LED strings from voltage sources ranging up to 400VDC.
The IL9921/22 includes an internal high-voltage switching MOSFET controlled with fixed off-time
TOFF of approximately 10µs. The LED string is driven at constant current, thus providing constant
light output and enhanced reliability. The output current is internally fixed at 20mA for IL9921,
50mA for IL9922 and 30mA for IL9923. The peak current control scheme provides good regulation
of the output current throughout the universal AC line voltage range of 85 to 264V AC or DC input
voltage of 20 to 400V.
