HV9921/22

Initial Release

3-Pin Switch-Mode LED Lamp Driver IC

Features

General Description

ꢀ

Constant Output Current:

HV9921 – 20mA

HV9922 – 50mA

The HV9921/22 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

include an internal high-voltage switching MOSFET

controlled with fixed off-time T_OFFof 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 and 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.
