在100mA下，+12 V输入转换器生成在 - 165V

上述电路产生-165V100mA时从+12V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>AppNotes>AUTOMOTIVEPOWER-SUPPLYCIRCUITSKeywords:+12VInputConverterGenerates-165Vat100mANov01,2000APPLICATIONNOTE435+12VInputConverterGenerates-165Vat100mAAdditionalInformation:qQuickViewDataSheetfortheMAX668qQuickViewDataSheetfortheMAX4130qTechnicalSupport:PowerThiscircuitusestheMAX668andatransformer(whichwillneedaboutaone-to-sixturnsratio)tomakeaflybackconverter.Theopampinvertsthefeedbackfromthenegativeoutputvoltage.Theabovecircuitgenerates-165Vat100mAfroma+12Vinput.BasedonaMAX668transformerflybackapplication,thecircuitemploysacustomtransformertogenerate-165Vthroughacombinationofturnsratioand
