3-Pin Switch-Mode LED Lamp Driver IC

The HV9922 is a pulse width modulated (PWM) high- ef, ciency LED Driver control IC. It allows ef, cient operation of LED strings from voltage sources ranging up to 400VDC. The HV9922 includes an internal high voltage switching MOSFET controlled with , xed off-time (T ) of approximately 10.5s. OFF The LED string is driven at constant current, thus providing constant light output and enhanced reliability. The output current is internally , xed at 50mA for HV9922. The peak current control scheme provides good regulation of the output current throughout the universal AC line voltage range of 85 to 264VAC or DC input voltage of 20 to 400V. By Supertex, Inc.
