“轨分离器” （图1中IC1）的配置提供了一个开关电容电压逆变器双极型（双轨），当地的电力供应，是有用的单轨系统具有一个或多个双轨集成电路。此外，微小的SOT-23封装及相关部件需要非常小的电路板面积。Maxim > App Notes > AUTOMOTIVE POWER-SUPPLY CIRCUITS Keywords: Voltage-Inverter IC Forms High-Efficiency Rail Splitter Aug 01, 1997 APPLICATION NOTE 1199 Voltage-Inverter IC Forms High-Efficiency Rail Splitter A switched-capacitor voltage inverter configured as a "rail splitter" (IC1 in Figure 1) provides a bipolar (dual- rail) local power supply that is useful in single-rail systems featuring one or more dual-rail ICs. Moreover, the tiny SOT-23 package and associated components require very little board area. Figure 1. This compact and efficient charge-pump circuit implements a local dual-rail supply for single-rail systems. After power is applied, the flying capacitor (C2) connects alternately across the storage capacitors C3/C4 and C5/ C……
