Part Number: SN6505A
one of my customers is planning too use the SN6505A with a Vin in the range of 4.5-5V. Sot hey follow in this case
So they will have a non regulated 5V line isolated but they need to obtain from it a 3.3V regulated voltage with I=300-350mA.
The question is, can they use a DC/DC converter instead of an LDO? Do you see any issues ?
In case they can, could you suggest a small Buck and efficient? On the PCB they don't have much space.
Thank you in advance.
Customer can use a DC/DC converter instead of an LDO at the output of SN6505A based isolated power supply without any issues. For device recommendations for buck converters, I would recommend you to reach out to DC/DC converter team. You can post the question in the Power Management forum to get devices suggestions. Thanks.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Koteshwar Rao:
thank you for the prompt reply!
I was wondering about the DC/DC since in the DS it's only specified to use an LDO. But your confirmation is clear.
Thank you for the recommendation.
Have a good day!
