Hi Shinichi,

Connections between TPS65994AD and HHD3SS460 are ok. TPS65994AD schematic also looks ok, although we generally recommend 330pF capacitance on CC1/2.

When configuring TPS65994AD, use the following GPIO configurations for GPIO 1, 2, and 3.

You can message me directly or respond here with any further questions.

Best,

Alex

Hi Alex,

Thank you for your reply.

I shared your suggestion with the customer and the customer has an additional question.

Could you please advise?

---

Currently 220pF is connected to CC1/CC2 to GND.

220pF is the value used in the datasheet.

Did you mention that it would be better to change 220pF to 330pF?

Or does that mean an additional 330pF capacitor is needed?

I appreciate your great help and cooperation.

Best regards,

Hi Shinichi,

Yes. We recommend changing the 220pF capacitor on CC to 330pF. So we recommend 330pF capacitance on each CC pin.

Best,

Alex
