Hello There

I have designed my own 65W PD power bank and have used your 45W power bank reference design  with CCG3PA a while back. Now i have my parts and programmer but cant seem to access to those ref design pages for schematics and software. I would like to know why those pages are disabled . Can you please send me schematic and software for said reference design so that i modify and use it for my own design? Thank you in advance.

Hi ,

You are correct that the page is removed. We are adding additional features and testing with latest USB-IF compliance tests. It will update on the page after the reference design is ready.

Best Regards,

Hello,

I have to re-direct you to CY4532 to begin to design power bank.

If you are very urgent, please kindly contact local Cypress FAE with your requirements, Cypress will supply reference design based on your requirements.

Best Regards,

Lisa

Hello there.

Thank you for your response. Yes i still need both schematics and firmware for the current/ old design. Ill be very thankfull if you could share it with me.

As for mosfets i used SIS415DNT-T1-GE3

And for GL i used CHY100D-TL which only supports up to Q.C. 2.0 but it works good enough for us.

Thank you and waiting for your reply.

Thank you very much ! Can you specify what was the problem? Which part didnt work ?

Oh i see why it did not work. Firmware you sent me is for Holtek MCU which is used in that reference design. What you and me need is firmware for CYPD3171 PSOC. Naturally if you tried the firmware you sent me to PSOC, it wont work. Do you have any other files , folders for this matter? maybe we can find much needed PSOC project between them ?
