Control circuit and control method for charge pump circuit |
| 摘要 |
A method of controlling a charge pump circuit can include: (i) detecting a difference between an output voltage and an input voltage in real time; (ii) generating an error amplifying signal by comparing the difference between the output voltage and the input voltage against a predetermined difference; and (iii) generating a control voltage signal for controlling the charge pump circuit according to the error amplifying signal, where a frequency of the control voltage signal positively changes along with the difference between the output voltage and said input voltage when the difference between the output voltage and the input voltage is greater than the predetermined difference. |
