Hello, We are using similar design of STEVAL-ISA203V1 with different transformer: CoilCraft POE600F-12LD. We see that there is very high current on the shunt resistors.

[EOvad.2]

The peak on the resistors is about 2V, and we are using 3 parallel 0.1ohm resistors -> causing the device not working and infinity retries.

We made a lot of experiments but for now, without any success.

Any suggestions?

I didn't find the datasheet of Coilcraft RA7133-BL in EVB? does anyone have it maybe?

Thank you,

Hi,
