TPS923655DRRREVM: Schematic and BOM required for TPS923655DRRREVM

Part Number: TPS923655DRRREVM
Other Parts Discussed in Thread: TPS923653DYYREVM, TPS923655DMTREVM

Tool/software:

I recently purchased TPS923655DRRREVM directly from TI.com, and it does not resemble the photo. Where the photo has one pair of screw terminals for the output, the board I received has three pairs, for input voltage, buck output, and buck-boost output.

I only have this PDF as a reference for the different variant's eval board: https://www.ti.com/lit/ug/sluuct0a/sluuct0a.pdf

It says Figure 6-1 shows the schematic for TPS923655DMTREVM. The only difference between TPS923655DMTREVM, TPS923655DRRREVM and TPS923653DYYREVM schematic is the main LED driver IC.

The board I received does not match this schematic. It has different connectors (three pairs of screw terminals instead of one) and I am finding details like the OVP divider must be using different resistor values than shown in the DMTR EVM schematic.

I shouldn't have to reverse-engineer this and doing so would risk missing something important. Please provide a schematic for the TPS923655DRRREVM, and specifically for the revision that you are currently shipping.

Thanks!
