TPS54239E: The frequency accuracy of TPS54239E

takahiko yokota

Part Number: TPS54239E

Fig10 of TPS54239E's datasheet is the characteristics at Ta=25℃.

Are there the data of any other ambient temperature?

My customer need the frequency tolerance.

Best regards,

Hi Yokota-san,

Below is the frequency data from temp char table. Ta=-40C to 85C. Only max, min and typical value are available.

Best,

Hi Anthony-san

Thank you for the the data.

I'm sorry for my delay response

Let me ask you a question in addition.

TPS54239E's Vin_max is 23V in datasheet.

But there are the frequency tolerance data at Vin=24V in the attatched document.

Is this deta correct?

Best regards,

Yokota

Hi Yokota-san,

I check again and it is indeed the validation data for TPS54239E. You could use it without worry. Thanks!

Best,

Anthony
