Switched-Capacitor Voltage Inverters _______________Detailed Description The MAX870/MAX871 capacitive charge pumps invert the voltage applied to their input. For highest perfor- mance, use low equivalent series resistance (ESR) capacitors (e.g., ceramic). During the first half-cycle, switches S2 and S4 open, switches ...

Switched-Capacitor Voltage Inverters Flying Capacitor (C1) Increasing the flying capacitor’s size reduces the output resistance. Small C1 values increase the output resis- tance. Above a certain point, increasing C1’s capaci- tance has a negligible effect, because the output resistance becomes ...
