Abstract

A pump circuit is disclosed. The pump circuit includes a first pump core circuit and a second pump core circuit. The second pump core circuit is coupled to the first pump core circuit. When a voltage value of a power source input to the pump circuit is not lower than a threshold voltage value, the first pump core circuit is operated and the second pump core circuit is not operated. When the voltage value of the power source is lower than the threshold voltage value, the first pump core circuit and the second pump core circuit are operated, so that a current value of the output current transmitted by the pump circuit is not lower than a threshold current value.
