摘要：
A charge pump having a supply terminal, for receiving a supply voltage, and an output terminal, for supplying an output voltage. The charge pump has a control block including a comparator having a first comparison input, for receiving the supply voltage, a second comparison input, for receiving the output voltage, and a comparison output, for generating a pump-switch-off signal depending upon a comparison between the input voltage and the output voltage; and a switch controlled in switching off by the pump-switch-off signal and configured for switching off the charge pump circuit. The control block has an activation input for receiving an activation signal that has a plurality of pulses and repeatedly activates the comparator-circuit block.
