电荷泵输入电流限制器
摘要：
一种系统可包括电荷泵和控制器，该电荷泵被配置为在多种模式下操作，该多种模式包括第一模式和第二模式，在第一模式下电荷泵的输出电压对输入电压的比率是第一比率，在第二模式下该比率是第二比率，该控制器被配置为通过响应于所述多个模式中的模式之间的操作的变化限制所述电荷泵的电源和所述电荷泵之间在电荷泵的一开关周期内的电荷转移来限制所述电荷泵的电源到所述电荷泵之间流动的电流，其中所述电源提供所述输入电压。
摘要（英）：

A system may include a charge pump configured to operate in a plurality of modes including a first mode in which the ratio of an output voltage to an input voltage of the charge pump is a first ratioand a second mode in which the ratio is a second ratio and a controller configured to limit current flowing between a power source of the charge pump to the charge pump, wherein the power source provides the input voltage, by limiting a transfer of charge between the power source and the charge pump during a switching cycle of the charge pump responsive to a change in operation between modes of the plurality of modes.
