Hi, I would like to know how to setting the I2t of the VNF1048F, what is the formula. thanks!

ST1S40 Max Current Problem On Different DC Sources

I made an DC-DC buck with ST1S40 in the simulations my output current is normal max 3A but in PCB i cant Load with 3A while using Chroma 6703.When i use my normal DC power supply i can Load with 3A and its not collapsing.I use GWINSTEK PEL-3041 Elect...
