A synchronous rectifier driver circuit outputs a gating signal to a synchronous rectifier of the synchronous converter responsive to the pulse width modulated input signal. An inhibit circuit inhibits the gating signal to the synchronous rectifier upon detection of a zero crossing condition. A circuit detects the zero crossing condition respective to comparing a measured value to a nominal value adjusted by a delta value.

摘要： A method drives a transistor half-bridge. The method includes measuring a delay time between an edge of an input signal and an corresponding edge of a phase signal, and saving the delay time as a saved delay time value. The phase signal is the output of the transistor half-bridge. In the method, the following steps are repeated until the saved delay time value differs from the delay time by more than a given threshold: decrementing the delay-value of a programmable delay circuit and the saved delay time value by a given decrement, the programmable delay circuit coupled to a control terminal of a first transistor of the half-bridge, and measuring the delay time between an edge of the input signal and an corresponding edge of the phase signal.

摘要： A method is disclosed for controlling a first transistor in a half-bridge circuit which also includes a second transistor. The transistors can be controlled by applying drive voltages to their gates. During a switch-off operation of the second transistor, the amplitude of the drive voltage of the second transistor is compared with a first threshold value and a second threshold value. A switch-on operation for the first transistor is started following a specified first period which begins at a first time when the drive voltage of the second transistor undershoots the first threshold value. The first threshold value is set in accordance with a second period which begins at a second time when the amplitude of the drive voltage of the second transistor undershoots the second threshold value. The second period ends at another time when the first transistor adopts a specified initial operating state during the switch-on operation.

In addition the drive circuit includes a second pulse width modulator which receives the second feedback signal and the periodic signal and generates the second pulse width-modulated signal.
