Hi Paul,

Issue we are facing is, external FET OC error is reported when I am driving at no load. I have measured the Vds at no load and it is above 0.5v average and reaching 0.9v at certain point. So we had to increase the Vds current limit in the driver to a very high value so that we can try even a small load. Please advise whether it is a layout issue is something else.
