The application circuit is shown in the following figure. In flyback applications, when the module works in intermittent and critical mode, the power works normally, and the chip driver and shutdown are better.When the module just enters the continuous mode, there is no problem with the work. Once the load continues to increase and the module enters the deep continuous mode, there will be the problem that the drive shutdown is not timely, resulting in the common phenomenon at the moment of switch. At this point, the peak voltage of tube Q1 at the moment of shutdown rapidly increases, and the product efficiency drops sharply.Please help to solve: can this product be applied to continuous mode?How to avoid and solve this problem?
