Abstract: A circuit includes a first transistor and a ringing control circuit. The first transistor is coupled between a power terminal and a switching terminal. The first transistor includes a first control terminal. The ringing control circuit is coupled between the power terminal and the first control terminal. The ringing control circuit includes a second transistor and a variable resistance circuit. The second transistor is coupled between the power terminal and the first control terminal. The second transistor has a second control terminal. The variable resistance circuit is coupled between the second control terminal and the switching terminal. The variable resistance circuit includes a control input coupled to the power terminal.

Abstract: A circuit includes a transistor and a ringing control circuit. The transistor is coupled between an input voltage terminal and a switching terminal. The transistor includes a control terminal. The ringing control circuit has a control input and a control output. The control input is coupled to the switching terminal, and the control output is coupled to the control terminal.
