TPS56C215: Recommended operating conditions :VIN

Part Number: TPS56C215

Hello team,

My client asked me about recommended operating conditions change on the datasheet.
He said that the minimum input voltage looks to be changed from 4.5V to 3.8V.
I found that the datasheet has revised recently in March 2018, but I can't find this change in the revision history.
I know this change is kind of a spec relax and no significant concern for users, but I'd like to know the background why and how the spec was updated.

Thanks in advance.

  • Hi,

    TPS56C215 could support 3.8V input if there is external 5V bias, If no external 5V bias, Vin_min keeps 4.5V. We add it to cover more applications.

    Thanks Vincent,
    I understood it. I hope it is described on the datasheet to avoid miss understanding.

    Hi Shinya,

    Actually we describe this features in two places. In Page 1 features, '4.5V start up without external 5V bias'; In page 7 EC table, add VIN UVLO with external 4.7V bias.
