TPS65251: Junction to board thermal resistance (vs TPS65251-X)

Jordan Dean
Prodigy 110 points
Part Number: TPS65251

We are looking for information regarding the datasheet value for Junction to board thermal resistance for the TPS65251 parts.

The datasheet value for TPS65251 is 73 C/W  (which seems extremely high)

The datasheet value for TPS65251-X is 8.2 C/W  

Can TI verify what the actual value for TPS 65251 is, if it's 73 C/W that would likely explain part of why we are having such difficulty with the part.

Thank you.

    Hi Jordan,

    Thanks for reaching out. And really thanks for pointing out this. Yes, the datasheet value for TPS65251 which is 73 C/W for junction to board thermal resistance is relatively high which is not correct. I suppose this should 7.3C/W which could be a typo.

    Thanks again for letting us know this.

    BRs
