TinySwitch with a Bug?
In the application document, the chip current limiting point will change with the load change.
In the document, it is introduced that the chip will have three overcurrent points as the load increases, such as 30%, 50%, 100%; As the load is reduced, there are also three overcurrent points, such as 100%, 70% and 30%, but in the actual test, I slowly increase the load, and I can see four different current limiting points, namely 30%, 50%, 70% and 100%. What is the reason for this? Is it an abnormal phenomenon?
