Product Overview

The HV9922N3-G is a 3-pin switch-mode pulse width modulated (PWM) high-efficiency LED Lamp Driver IC allows efficient operation of LED strings from voltage sources ranging up to 400VDC. The HV9922 includes an internal high voltage switching MOSFET controlled with fixed off-time (TOFF) 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 fixed 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 265VAC or DC input voltage of 20 to 400V.
  • Universal 85 to 265VAC operation
  • Fixed OFF-time buck converter
  • Internal 475V power MOSFET
