This is a company of development and producing wireless and power systems located in Tokyo Japan.
We are currently developing a fast charging (6C) mobile battery under contract from a charger manufacturer, and we will be using USB PD as the output interface.
Your agency, MARUBUN CORPORATION, introduced your product lineup for USB PD, and we have decided to use the attached product (please refer to the attached block diagram).
We would like to complete the prototype within this month, so we would like you to confirm that there are no problems with the circuit diagram we have created, so we have submitted the circuit diagram to MARUBUN CORPORATION in middle of August.
However, I still have not received any comments.
Therefore, I will send you a circuit diagram as attached, and we would appreciate it if you could check it and point out any problems.

Dear sir.
As per your advice, I accessed MPS NOW Technical Support-Contact, but after receiving the attached announcement, I have not received any contact.
In the first place we have requested MPS Japan through your agency, MARUBUN CORPORATION, in mid-August, and asked it many times but they said "US side no reply"and so they can not reply anything.
That is why I am asking for your help.
Could you please help me?
thanks and Best Regards.

Thank you for reaching out.
