please review the scope waveform below.
Question #1: Is this the correct waveform for pin #3?
COMMENT: This waveform seems out of place compared to the other IC waveforms.
I have replaced the Vsense resistor with a trim pot so that I could vary the voltage from 1-volt to 3-volt. The Vvao always remain about the same voltage.
From what I understand is the Vvao should be higher than the Vsense.
Question #2) Should Vvao be higher than Vsense OR what should the voltage be?
Question #3) Looking at the Measure All Data, is there any reading that appears wrong/off?
Question #4) At what voltage should Vvao be greater than Vsense?
Question #5) With this information can you possible see why I do not get any output waveforms Pin 14 & 17?
