LSF0108-Q1: The output voltage of A side is limited by VrefA

Part Number: LSF0108-Q1
Other Parts Discussed in Thread: LSF0108,

According to the description of the following video, the A side of LSF0108 should be able to output a voltage higher than VrefA, such as 3.3V in the video. But when we use LSF0108-Q1 , it was found that the output voltage of side A was limited to 1.2V, which could not be changed even if it was pulled up to 3.3V. What's the reason? Thank you.
