摘　　要：基于开关电容的倍压器又称为电荷泵,设计将电荷泵集成到一颗芯片中。该芯片能够在4 V至20 V的输入范围内工作,并提供7 V至38 V的输出,提供超过10 mA的输出电流。电路采用电荷泵结构实现倍压,该电路的特点是无需电感,就可实现对输入电压的倍增,消除了电磁干扰的影响。空载情况下电源电流最大不超过12 mA。另外该电路采用双极型工艺制造,不易发生闩锁。The switched capacitor voltage doubler is called charge pumps.It is integrated into a chip.Capable of operating from a 4 V to 20 V input,it provides±7 V to±38 V output.Output currents of over 10 mA are available.This circuit adopts charge pump structure to realize voltage doubling.The characteristic of the circuit is that the input voltage can be doubled without inductance,and the influence of electromagnetic can be eliminated.The maximum power supply current under no load is not more than 12 mA.Manufactured in bipolar technology,that is not susceptible to latchup.
