LM5148-Q1: Loop Stability Testing in Programmed Output Mode

Part Number: LM5148-Q1

Tool/software:

Will injecting a test signal into the FB pin still work for gain and phase margin testing if the device is configured with a pull-up to VDDA?

If not, how can I test stability?

I'm using a 0Ω pull-up to VDDA to configure for 3.3V output at 24V input. I'm using external compensation. I have spread spectrum and DCM configured.

The supply is working fine at nominal conditions, but I would like to know for sure it will be stable.
