I need your urgent help to understand the failure in our PCB.
We had designed the Analog feedback loop to control current through MOSFET as we are using mosfet as virtual load.
when we were using this LOOP with SiE844DF Mosfet, everything was working good but in new PCB , the whole design is same except the mosfet . Now we are using SiDR220DP MOSFET with same loop.
Please let me know where we are doing wrong, is there need to change this loop gain or something?
if yes, please help to tune this loop.
I have attached schematic of Analog loop, Mosfet, and ltspice file for complete loop.
We are currently looking into this. We'll get back to you soon.
Thanks a lot for your reply.
Please help to tune the Analog loop with SiDR390DP instead of SiDR220DP.
Thanks for your time.
Please let me know for any other info needed or any other file needed.
I would really appreciate if you can help me in solving this issue.
I am not able to tune the analog loop with SiDR390DP.
Please help me.
