Part Number: TPS7B63-Q1

Hi all,

In the upper left of P.15 of TPS7B63-Q1 's datasheet, it is described as PWP0016J.

Looking at other IC data sheets of the same package type (HTSSOP), there are PWP0016A, PWP0016D, etc.

These differences seem to be the size of THERMAL PAD.

Why are you changing the THERMAL PAD size with the same package type?

Hi Koji,

The variation comes from the package type being manufactured at multiple sites. There is no industry standard on the thermal pad size and TI has acquired several companies who used different sized thermal pads.

Very Respectfully,
Ryan

Hi Ryan-san

Thank you for quick response.

Products planned for use by customers are those of the same factory, but the thermal pad size is different.
Are there other reasons?

Best Regards,

Hi Koji-san,

There should only be one thermal pad size for a single device at a single factory. The thermal pad size can vary by leadframe so if a factory has two different products that have different leadframes, the dimensions of the thermal pad may be different.

Very Respectfully,
Ryan
