Abstract
The present invention provides a control method and a control circuit for a switch circuit and a corresponding switch circuit device. The control circuit comprises: an acquiring module, configured to acquire first time; a comparing module, connected with the acquiring module and configured to compare first time with first fixed time; and an adjusting module, connected with the comparing module. The adjusting module adjusts a cycle of a turn-on signal of a first switch transistor to second fixed time when the first time is less than the first fixed time. The adjusting module adjusts the sum of second time and the first fixed time to the second fixed time to achieve spread spectrum when the first time is more than the first fixed time. The control circuit for the switch circuit provided by the present invention is used for controlling the switch circuit for spread spectrum.
