Abstract
A pulse frequency modulation switching regulator varies the forced off-time of a load circuit when the load circuit is subject to an overload or short circuit event. An on-switch of the circuit is deactivated for a variable time interval when an output current of the load circuit exceeds a threshold. The time interval that the on-switch is deactivated is dependent on an output voltage of the load circuit. The on-switch is deactivated for a short time interval when the load circuit is subject to a slight overload. The on-switch is deactivated for a long time interval when the load circuit is subject to a short circuit.
