Abstract
The disclosure provides an over-current protection circuit. A signal generating block in the over-current protection circuit generates one or more input voltages, a summed voltage and an average voltage in response to one or more differential voltages. A control block generates one or more control signals in response to the one or more input voltages and the average voltage. An analog control loop block generates an initiation signal in response to the summed voltage and an output voltage. A phase control logic block generates one or more PWM (pulse width modulated) signals in response to the initiation signal and the one or more control signals.
