The disclosure relates to a voltage adjustment device, a power chip and electronic equipment. The device comprises an input module, a clamping module, a first transistor, a second transistor, a control module and an output module, wherein the control module is electrically connected to the first end of the input module and the output module and is configured to, when the difference between the output voltage and the input voltage output by the output module is less than or equal to a preset value, output a pulse width modulated PWM signal to the gate end of the second transistor, input an input voltage to the gate end of the first transistor within a preset duration, and output a clamp signal to the gate end of the first transistor when the preset duration is reached, so as to clamp the voltage difference across the input module to the first voltage. The voltage adjustment device provided by the disclosure can keep the system stable when the mode is switched, and can maintain the voltage adjustment efficiency of the voltage adjustment device at a high level, thereby improving the voltage adjustment efficiency and reducing energy loss.
Description
technical field [0001] The present disclosure relates to the technical field of integrated circuits, in particular to a voltage adjustment device, a power chip and electronic equipment. Background technique [0002] Voltage adjustment technology is widely used in electronic equipment. Due to the diversity of people's needs, the rated working status of different types of electronic equipment is also different, so technicians need to use voltage adjustment technology to adjust the same type of electric energy to meet The working voltage required for the safe operation of electronic equipment to ensure that the electronic equipment can always be in a stable state. The voltage adjustment circuit can ensure that the power system can be compatible with the power supply requirements of various types of electronic equipment, and different electronic components can be connected to the adjusted electric energy to meet the different circuit function requirements of users, so that the d...
