Team,
we would like to build an isolated DC/DC power supply:
I found candidates like LM34925 and LM5160A. One concern is that transformer is not from the shelf, but special one (?).
Can you please check requirements and suggest which type would be recommended?
Thank you.
Hi Bart,
The LM5180 will be the simplest solution for this.
Please look through the datasheet and the 5V application.
Using the design calculator here under "Development Tools" it looks like a 4:1 transformer will be your best choce.
However the output power is limited (not current) so the output voltage will drop out over-current conditions.
Try using the Design calculator and let us know what you think.
