Hi Stefan,

May we know what application your design will be used? Thank you very much.

Hi PI-LeoDavinici,

i would like to use it as a power supply for a stepper motor drive in a small home application.

Hi Stefan,

You may want to consider the following designs using Power Integrations LinkSwitch or TopSwitch products. You may modify the design a little bit to satisfy your requirement. Hope this helps as a starting reference. Thank you very much.
