降低振荡器频率和增大外接电容量可以改善ICL7660电压转换电路的转换效率。尽管这种技术对普通的I_O是有用的,但这并没在技术资料中清楚地加以描述过(采用8引脚DIP或TO-99密封外壳式封装的CMOS ICL7660是一种电荷泵器件,它把1.5V到10V的输入电压转换成对应的从-1.5V到-10V的负输出电压)。
Lowering the oscillator frequency and increasing the external capacitance can improve the conversion efficiency of the ICL7660 voltage conversion circuit. Although this technique is useful for normal I_O, it is not explicitly described in the technical literature (CMOS ICL7660 in an 8-pin DIP or TO-99 Sealed Encapsulation is a charge-pump device that Convert 1.5V to 10V input voltage to corresponding negative output voltage from -1.5V to -10V).
