Abstract: An apparatus includes: a first transistor coupled between a primary-side terminal and a bias terminal, the first transistor having a first control terminal; a second transistor coupled between the bias terminal and a ground terminal, the second transistor having a second control terminal; and a control circuit having a control input, a reference input, and first and second control outputs, the control input coupled to the bias terminal, the first control output coupled to the first control terminal, the second control output coupled to the second control terminal, and the control circuit configured to provide first and second control signals having a same switching frequency at the respective first and second control outputs responsive to a first voltage at the control input and a second voltage at the reference input.
