Abstract
An over-current protection device for use in a switched mode power supply prevents over-current conditions caused by short-circuits faults. The over-current protection device monitors a current in the switched mode power supply, and in particular, determines a peak current value associated with the monitored current. The monitored current is compared to a reference value to determine whether an over-current condition exists. If an over-current condition is detected, then the over-current protection device modifies the ‘off’ time of the switched mode power supply based on the determined peak current value.
