Other Parts Discussed in Thread: LM3481, TIDA-00744, TPS55340
Hi,
I have noticed some discrepancies in this video regarding what Mr. Xiang was telling and what he had showed.
Video Link: https://www.youtube.com/watch?v=78UR5jJQj4Y
- Video time 5:35: He was explaining that the Boost Converter is in bypassing mode but according the schematic PMP9477 Rev. 3 this circuitry for bypassing mode is not populated. This can be also noticed at Video time 2:58 where U4 is not populated. Could someone explain how the LM3481 will be setup in the bypass mode?
On the other Hand, a reference design TIDA-00744 Rev. E1 have the bypassing circuit with transistor Q1. This circuit can not be found in PMP9477 schematic. Could you explain why?
- Video time 5:18: He said 2V/Div and 12V Input, but from my point of view it looks like 11V. Is that correct?
- Video Time 5:50: If the Channel 1 (VIN) and Channel 2 (VMID ...Boost output) have the same reference 0V Position, then the VMID will be 8V. Correct?
Why the PMP9477 Rev. 3 Schematic states 9.5V 1.5A?
I am quite confused regarding this presentation.
Best regards,
Josko
