HV9921/HV9922/HV9923  
Initial Release  
3-Pin Switch-Mode LED Lamp Driver ICs  
Features  
General Description  
The HV9921/22/23 are pulse width modulated (PWM)  
high-efficiency LED driver control ICs. They allow efficient  
operation of LED strings from voltage sources ranging up  
to 400VDC. The HV9921/22/23 include 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  
HV9921, 50mA for HV9922, and 30mA for the HV9923. 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.  
Constant Output Current:  
o HV9921 – 20mA  
o HV9922 – 50mA  
o HV9923 – 30mA  
Universal 85-264VAC Operation  
Fixed OFF-Time Buck Converter  
Internal 500V Power MOSFET  
Applications  
Decorative Lighting
