Abstract
The present invention relates to a power supply with output protection and a control method of the power supply. The invention mainly provides a pre-protection value lower than a default over-current protection value. When a present output current of the power supply is higher than or equal to the pre-protection value and is lower than the over-current protection value, the method firstly determines whether the power supply has abnormal conditions. When the power supply has abnormal conditions, the method can automatically provide or stop providing a working voltage to a load. When the present output current is further higher than or equal to the over-current protection value, the method takes an over-current protection action. By multi-level monitoring of the current values, the invention properly provides an over-current protection.
