摘要:Disclosed is an SMPS protection circuit, which can prevent unnecessary electricpower consumption that may be caused due to a light load as well as damage of theSMPS protection circuit caused by a heavy load. According to the SMPS protection circuit,
a voltage lowered by the load is fed back. If the fed-back voltage corresponds to thelight load, the switching frequency of an SMPS transformer is downed. If the fed-backvoltage corresponds to the heavy load, the SMPS protection circuit ceases to operate.
