Abstract

The present invention relates to a control circuit arrangement for pulse-width modulated DC/DC converters. The arrangement comprises a phase generator (10) for a complementary driver (20) adapted to provide respective gate signals to a first and second driver transistor in response to a control signal (p_off_pwm). A clock control circuit (30) receives a clock signal (x_clk) and a pulse-width modulated signal and provides the control signal (p_off_pwm) in response to a signal edge of the pulse-width modulated signal and the clock signal (x_clk) 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 is adapted in the first mode to provide each of the gate signals in response to the control signal and in response to the respective other gate signal. In the second mode of operation, it provides each gate signal in response to the control signal.
