HV9922N8-G 技术参数

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 T_OFF

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

ꢀ Low Power Lighting Fixtures
