HV9921/HV9922/HV9923

3-Pin Switch-Mode LED Lamp Driver ICs

Features

Description

HV9921/HV9922/HV9923 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. 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 out-

put current is internally fixed at 20mA for HV9921,

50mA for HV992, and 30mA for HV9923. The peak cur-

rent 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:

- HV9921 – 20mA

- HV9922 – 50mA

- HV9923 – 30mA

• Universal 85 - 264VAC operation

• Fixed off-time buck converter

• Internal 475V power MOSFET

Applications

• Decorative lighting

• Low power lighting fixtures
