摘要：这样的设计理念，展示了如何规范的LCD偏压发生器无需电感。基于MAX868稳压，反相电荷泵电荷泵的设计取代了开关模式设计，以产生一个负电压偏置的LCD。负，反相电荷泵的反馈路径中几个组件生产逆变器四倍频电路。Maxim>AppNotes>DisplayDriversKeywords:switch-modepowersupply,chargepump,regulatedchargepump,invertingchargepump,regulatednegativevoltage,inverterDec17,2001quadrupler,personaldigitalassistant,PDAAPPLICATIONNOTE239RegulatedLCD-BiasGeneratorRequiresNoInductorAbstract:ThisdesignideashowshowaregulatedLCDbiasgeneratorrequiresnoinductor.Acharge-pumpdesignbasedontheMAX868regulated,invertingchargepumpreplacesaswitch-modedesigntogenerateanegativevoltageforbiasinganLCD.Afewcomponentsinthefeedbackpathofanegative,invertingchargepumpproduceaninverter-quadruplercircuit.AsimilarideaappearedintheMarch9,1998issueofElectronicDesign.Astringentheightlimitationon……
