TPS55010EVM-009: Discrepancy in R10 value

Robert Helvestine

Part Number: TPS55010EVM-009
Other Parts Discussed in Thread: TPS55010

Forgive me if this has been posted already, but R10 in the TPS55010EVM-009 is mislabeled as a 10k resistor in the schematic, when in fact it is a correct 61.9k resistor in the BOM:

This is a bit disappointing, as the TPS55010 (part, not dev board) datasheet uses an R10 value of 10k, and the handy spreadsheet that comes with the documentation uses a 10k resistor as well. So it took a while to figure out why my dev board was not working when this resistor was assumed to be 10k.

Just opening this up to a wider audience. Thanks.

Hi Rob,

Thank you for pointing this out. I hope it didn't cause you too much trouble. I looked at the build files and the same error exists; the schematic shows one value but the BOM shows another. I will get the schematic for the EVM in the user's guide updated to match the actual BOM.

Best Regards,
Anthony

Thanks Anthony. I would recommend changing the BOM to match the schematic, so that the R10 value is 10k, which matches the TPS55010 datasheets examples and example spreadsheets provided with the documentation.
