Average input current limit method and apparatus thereof
摘要:
The embodiment of invention discloses an average input current limit method and apparatus thereof. The apparatus comprises a switching circuit, a current average circuit and a current limit circuit. The current average circuit samples the input current of the switching circuit and generates a signal representative of the average value of the input current. The current limit circuit limits the signal so as to limit the average value of the input current.
