    摘要： A control circuit arrangement for pulse-width modulated DC/DC converters includes a phase generator for a complementary driver which provides respective gate signals to a first and second driver transistor in response to a control signal. A clock control circuit receives a clock signal and a pulse-width modulated signal and provides the control signal in response to a signal edge of the pulse-width modulated signal and the clock signal applied thereto. A mode selection input terminal receives a mode selection signal to select a first mode or a second mode of operation. The phase generator provides in the first mode each of the gate signals the control signal and the respective other gate signal. In the second mode of operation, it provides each gate signal in response to the control signal.
