Isolated synchronus Step-Down Converter ?

Other Parts Discussed in Thread: LM5015, LM43603

Hi All,

it seems to be easy to find an appropriate Converter within this huge amount of devices - but I could'nd get out right one:

http://www.ti.com/power-management/offline-isolated-dcdc-controllers-converters/isolated-dcdc-converter/products.html      (LM5015 - iout=1,4A max)

Step-Down Converter suitable for a isolated design - alternatively also as non-isolated design:

Vin=20...30VDC
Vout=10VDC
I_Out=3A

Synchronus design with high efficient internal Switches and powerpad package
FEEDBACK Pin using internal Regulator for a non-isolated regulation
COMP Pin using external secondary Regulator with optocoupler for
(One layout, different assembly)

What is the next closest Controller device?

Thank's for answering @ eduard.mathies@inficon.com

Regard's

Eduard Mathies

    I apologize for the delay on our response, for a non-isolated solution please take a look at the LM43603 device as an alternative. For isolated solutions you need to search for a Fly-back controller.
