Layout example of TPS7A7100

Other Parts Discussed in Thread: TPS7A7100

Hi

In datasheet, there is the layout example of RGW.
If there is layout example of RGT, could you give me it?
Best regards,
Yokota

    Hi Yokota,

    The section in the datasheet that you refer to is meant to convey layout concepts. These same concepts should be applied to the RGT package as well; however, we do not have a drawing of the RGT package at this time.

    Very Respectfully,

    Hi

    I would like to ask you about 10.1 Layout Guidelines of TPS7A7100.
    The OUT terminal and the GND terminal of TPS7A7100RGT are far.
    So, I think it is difficult to meet two, four and fifth in it.
    Can I get advice about RGT package's layout?
    Best regards,
    Yokota

    Hi Yokota,

    These principles can still be followed with the RGT package, much in the same way as shown in the example drawing for the RGW package.

    Below I have shown the differences between the two pinouts.  All of the recommendations with be the same between the two packages except for the output capacitor.  The output capacitor will need to be rotated and placed similar to the input capacitor.  The output capacitor will be parallel to the FB resistor network in this case and PG would still drop through a via to be routed to the desired location.

    Very Respectfully,

    Ryan
