Systems and methods for adaptive switching control in power conversion systems

An apparatus comprising:

• an input terminal configured to receive an input signal;
• a first comparator coupled to the input terminal and configured to compare the input signal to a first threshold and to generate a first signal in response to the input signal exceeding the first threshold;
• a first circuit coupled to the first comparator and configured to initiate a first interval in response to the first signal;
• and
• a second comparator coupled to the input terminal and configured to compare the input signal to a second threshold and to generate a second signal based on a comparison between the input signal and the second threshold, the second threshold being greater than the first threshold;
• wherein the first circuit is further configured to adjust the first interval based at least on the second signal.

An apparatus comprising:

• an input terminal configured to receive an input signal;
• a first circuit coupled to the input terminal and configured to provide a control signal based at least on the input signal;
• a driver coupled to the first circuit and configured to receive the control signal;
• a first transistor coupled to the driver, the driver being configured to activate the first transistor in response to the control signal;
• and
• a second transistor coupled in parallel with the first transistor, the second transistor being configured to be activated after the first transistor.
