上述电路产生- 165V 100mA时从+12 V输入。基于MAX668变压器反激应用上，该电路采用一个定制的变压器匝数比和占空比组合产生165V通过。 SG5型，大小骨架以方便绕组和减少漏感变压器的设计。Maxim > App Notes > AUTOMOTIVE POWER-SUPPLY CIRCUITS Keywords: +12V Input Converter Generates -165V at 100mA Nov 01, 2000 APPLICATION NOTE 435 +12V Input Converter Generates -165V at 100mA Additional Information: q Quick View Data Sheet for the MAX668 q Quick View Data Sheet for the MAX4130 q Technical Support: Power This circuit uses the MAX668 and a transformer (which will need about a one-to-six turns ratio) to make a flyback converter. The op amp inverts the feedback from the negative output voltage. The above circuit generates -165V at 100mA from a +12V input. Based on a MAX668 transformer flyback application, the circuit employs a custom transformer to generate -165V through a combination of turns ratio and ……
