Linear Tech Isolated Micro Modules

Hi all,

Has anyone had any experinece of using LT's isolated micro modules? I am looking to design a simple isolated 5v converter but space is constrained and these look pretty simple to set up, integrated transformer is useful too.

Has anyone designed these into a product and if so how well do they work? I know that its cheating really, not having to do many calculations, and closing the feedback loop etc (half the fun has gone :( ) but space is at a premium and the application is for a very low power supply...

Best regards

Do you need 5V converter from what Vin range? is DC/DC converter? or AC/DC?

To AC Mains to 5VDC converter, the issue with the isolated designs is the transformer bulk height. I have a 35V 0,3A supply from the AC mains, in a 3x3x1cm space, but is not isolated, with the IC: Viper22A. changing other components you can have 5V/ 0.3A.

There is other IC: FSAR001 of fairchildsemi, that allow few external components to have 5V from AC mains, but this is a not isolated system.

If isolated is a must, the near design is the 1"x1" cube like the actual USB chargers.

Hi Luke..

The LT modules are easy to use and are small. They work well

Use the UCC28710 from TI...much more stable design.
