A charge pump is a kind of DC-to-DC converter that uses capacitors for energetic charge storage to raise or lower voltage. Charge-pump circuits are capable of high efficiencies, sometimes as high as 90–95%, while being electrically simple circuits. Web电荷泵（charge pump），也称为开关电容式电压变换器，是一种利用“快速”（flying）或“泵送”电容（非电感或变压器）来储能的DC-DC变换器。. 电荷泵能使输入电压升高或降低，也可以用于产生负电压。. 其内部的FET开 … WebAudio PA • Mono : SGM4891 SGM4995 • Stereo : SGM4863 SGM4865 SGM4888 (3D) • Headphone: SGM4914 SGM4915. 封装成本低， 未来音频趋势.
