Hello,
I am using on my board STM32H755XIH6 CPU and I connected the SMPS feature.
The board voltage is 3.3V, the SMPS regulate the voltage to 1.8V and supplies the LDO.
I am using VOS1 and right now it's working WELL at room temperature.
I measured the VLXSMPS and I want to be sure if the overshoot and undershoot is ok?
can the component be damaged from this overshoot and undershoot?
can you explain to me why I see this?
