TPS568215: VREG capacitor to PGND or AGND?

Davide Scandagli

Part Number: TPS568215

Hi,

the the byass capacity to the VREg pin must be connected to the dedicated AGND (like datasheet) and then connected in a single point to the PGND or directly to the PGND (like TPS568215EVM-762).

Hi,

If you do not apply an external voltage on VREG5 pin, connect the bypass capacitor to AGND. If an external voltage applied, you could connect the capacitor to PGND which should be the same GND with the external source.
