Digital switching converter control
Abstract:
A control circuit can control the operation of a switching converter to provide a regulated load current to a load. The switching converter includes an inductor and a high-side and a low side-transistor for switching the load current provided via the inductor. A digital modulator is configured to provide a modulated signal having a duty cycle determined by a digital duty cycle value. A current sense circuit is coupled to at least one of the transistors and is configured to regularly sample a load current value. A comparator is coupled to the current sense circuit and is configured to compare the sampled load current value with a first threshold and to provide a respective comparator output signal. A regulator is configured to receive the comparator output signal and to calculate an updated digital duty cycle value.
