Abstract
The disclosure provides an electronic device that includes a first circuit board, a second circuit board, a charge pump chipset, a battery, and a control component. The charge pump chipset can be coupled to the battery, and include at least two charge pump chips provided on the first circuit board and at least two charge pump chips provided on the second circuit board. The control component is configured to control one charge pump chip on the first circuit board and at least one charge pump chip on the second circuit board to be in a working state at the same time and, in response to a temperature of the charge pump chip on the first circuit board in the working state being higher than a set threshold, to switch any charge pump chip on the first circuit board with the temperature lower than the set threshold to the working state.
