Hi,
I am working in the isolation stage of an ultra-low power application. I need to produce an isolated power supply for the isolated side and I have not found an Isolated DC/DC 3.3V to 3.3V efficient at less than 2mA of current.
The most adapted solution that I found in analog is the Adum5028 (less than 20% of efficiency at 2mA). Is there another one that is more efficient? Also, if the solution comes in a small footprint, way better.
Thank you,
Gustavo
