Abstract
A negative over-current protection circuit for a switching inverting converter is provided. The circuit contains an energy-storing element coupled to a power switch via a switching node, a current sensor adapted to sense a current at the switching node and to convert the current into a voltage. The circuit also contains a converter adapted to convert the voltage into a first current associated with a first domain, a level shifter adapted to convert the first current into a second current associated with a second domain and a current comparator adapted to compare the second current with a reference current and to provide a logic signal based on the comparison. A method of protecting a switching converter from an over-current is also provided.
