Super power delay turn-off protection is a kind of output overload protection technology which is necessary in the development of power adapter. In the delay tripping system, the requirement of short time transient current is allowed only when the current stress exceeds the safe value for a long time before the power supply is turned off. The supply of short transient current will not harm the reliability of the power supply, nor will it have a great impact on the cost of the power supply. Only the requirement of temporary continuation of current will affect the cost and volume of the circuit.
