Is there a way of margining the output of the LM3668-4550? I would like to vary +/-mVolts to +/- 10ths of a volt around 4.5V with Vin=3.3V+/-10%. This would not be for normal operation - just for verification in my circuit.
One thought I had was to either vary Vfb or Vsel. If it can be margined - what is the maximum deviation around 4.5V that is achievable? Again - I'm only looking to be able to margin <1Vdc.
Thanks in advance!
