Using LM2679T-12/NOPB, a circuit that outputs 24V input to 12V/5A was constructed.
Measuring the output terminal measures 12V.
However, when a load of 12V/1A is applied, only about 3V to 4V is output.
What's wrong with my circuit?

I see you have a similar thread here (https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1102980/lm2679-when-a-load-is-applied-a-low-voltage-is-output) and so I will close this thread in order to consolidate the troubleshooting effort.
