Abstract:
An apparatus comprises a synchronous converter for providing a regulated output voltage responsive to an input voltage, a control PWM signal to a control switch of the synchronous converter and a synchronous PWM signal to a synchronous switch of the synchronous converter. A first circuit generates the control PWM signal and the synchronous PWM signal responsive to a PWM control signal. The first circuit limits a maximum duty cycle of the synchronous PWM signal to a predetermined level.
