Abstract:
The present invention discloses a method and a circuit for reducing switching ringing in a switching regulator. The switching regulator comprises two transistors, and the two transistors are never simultaneously OFF. A phase lock loop may be provided to fix the output signal frequency of a PWM control circuit to a set frequency.
