Hello everyone, I have prepared a synchronous step-down converter. In this design, I use the STM32F303RE as the controller. In the schematic, I take measurements over the resistors I took in the green square and turn off the gate signals of the Mosfets in case the current exceeds the limit. Since I perform a soft start application in the controller, there is no inrush current status at the start. However, after running the system for a while, the system turns off due to the current limit. What could cause this?
