Part Number: LMR33630
Hello,
We have built a USB-C PD 45W charger using the LMR33630 with a Vin=27V to step it down to 5, 9, 15, 20V at 3A maximum.
We have come across some issues, which are detailed in the post below:
https://e2e.ti.com/support/interface/f/138/p/846203/3133045
Is it possible that there is an issue with the LMR33630 that is causing that behaviour?
We have used another custom DC-DC converter instead and the TPS65987DDJ behaves exactly in the same way, so our impression is that it is not a possible stability/protection issue of the LMR33630.
However, to be absolutely sure, thought I would ask here just in case.
Thank you very much.
Kind regards,
Vyron
