  Part Number: LM3880-Q1 Team, Is the LM3880QMF-1AE/NOPB logic bearing? I believe the reason for this question is because if it is programmable then there is a supply chain risk that my customer needs to manage/mitigate. Thank you.

  Part Number: LM3880 awg_2v11 pg 22 to 26.pdf U54 on the first page did not turn on. I believe it follows the recommended circuit exactly (Figure 20). The EN voltage is ~ ground. Feedback would be appreciated.
