Abstract
A power supply circuit of a terminal device includes a voltage boost circuit, a battery chip, and a controller. The battery chip is configured to provide an output voltage of a battery for a load. An input end of the voltage boost circuit is connected to a positive electrode of the battery, and an output end of the voltage boost circuit is connected to the load. The output voltage of the battery is boosted when the temperature is relatively low or the output voltage of the battery is relatively low. In addition, when a relatively high pulse current occurs on the terminal and the output voltage of the voltage boost circuit is stepped down, both the battery chip and the voltage boost circuit is controlled to supply power to the load.
