Abstract
A converter coupled to a DC voltage input and connectable to a load, includes a signal responsive switch coupled between a first circuit point and a second circuit point. Current flow is directed by the switch, when in a closed state, to the second circuit point to bypass the load. A regulator circuit has an output coupled to a control input of the switch. The regulator circuit has a first input for receiving a sensed load parameter, a second input for receiving a sensed current level signal at the second circuit point when the switch is in its closed state, and a third input for receiving a sensed current level signal at the second circuit point, measured directly, when the switch is in an open state. A fixed minimum time is set for the switch to be in the open state. The third input inhibits re-closing of the switch, providing current limit protection for the switch.
