Mode control device, voltage converter, and control method used in the voltage converter
A voltage converter can include a voltage conversion circuit having an inductor configured to be charged and discharged to facilitate conversion of an input voltage to an output voltage, and a switch configured to allow the inductor to be charged and discharged. The voltage converter can further include a logic drive unit configured to provide a drive signal to the switch to control the charging and discharging of the inductor. The voltage converter can further include a mode control unit configured to provide a mode-switching signal to the logic drive unit to control switching between a continuous control mode and a discontinuous control mode based on an inductance current associated with the inductor and a constant load-current threshold.
