Abstract
Disclosed are a phase-tracked pulse generation circuit and a power supply device. The present application uses a driving pulse rising edge of a power supply as a reference, and uses a constant current circuit to charge a charging and discharging circuit at a constant current. When the reference driving pulse rising edge comes, the charging and discharging circuit is discharged; the peak voltage on the charging and discharging circuit is taken out and then divided for comparison with the voltage on the charging and discharging circuit; when the voltage on the charging and discharging circuit is equal to a divided voltage value of the peak voltage, the output of a comparison circuit turns high, and the output of a comparator is the phase-tracked pulse; the rising edge of the phase-tracked pulse can be used for synchronizing another power supply.
