UCC28180: Unstable output when increasing load

Part Number: UCC28180

I'm using UCC28180 for 180V power supply.

With <2A load, output is quite stable. As I increase the load to around 3 A the Vout starts becoming unstable.

What should I check?

Thanks

Hello John,
You should use the Excel calculator tool for this part and make sure that you are using the correct component values.
Please fill out the data for this tool and compare it to the values you now have in your circuit
Regards
John
