急,求直流75V輸入LED驅(qū)動電源方案
要求:DC 75V輸入,分別為帶載120V,145V,200V,100mA正負10mA輸出!有沒有那位大哥有現(xiàn)成的方案啊?給小弟介紹介紹,不勝感激
全部回復(fù)(8)

閣下可以看下NS的LM5118.LM3402HV.
LM3402的特性:
--------------------------------------------------------------------------------
? Integrated 0.5A N-channel MOSFET
? VIN Range from 6V to 42V (LM3402)
? VIN Range from 6V to 75V (LM3402HV)
? 500 mA Output Current Over Temperature
? Cycle-by-Cycle Current Limit
? No Control Loop Compensation Required
? Separate PWM Dimming and Low Power Shutdown
? Supports all-ceramic output capacitors and capacitor-less outputs
? Thermal shutdown protection
? MSOP-8, PSOP-8 Packages
