供应安森美芯片nsi45030Zt1G;替换为V9921

features constant output current: o v9921 – 20ma o v9922 – 50ma o v9923 – 30ma universal 85-264vac operation fixed off-time buck converter internal 500v power mosfet applications decorative lightinglow power lighting fixtures general deaaion the v9921/22/23 are pulse width modulated (pwm) high-effi ciency led driver control ics. they allow effi cient operation of led strings from voltagesources ranging up to 400vdc. the v9921/22/23 include an internal high voltage switching mosfet controlled with fi xed off-time toff of approximately 10μs. the led string is driven at constantcurrent, thus providing constant light output and enhanced reliability. the output current is internally fixed at 20ma for v9921, 50ma for v9922, and 30ma for the v9923. the peak current controlscheme 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
