John - I've got several CK1414s variants myself - glorious beasts - what mask set do yours have? Not had much time to do anything with mine yet - they are all alphanumeric with a few special characters - probably used for airport information displays etc. Yeah, mine also has

That would be awesome. Please add me to the list of buyers. Marcin On 13/08/2013 10:55, taylorjpt wrote: 24Vin, 80W out at 308V: http://ppl.ug/iOtLwdq3aFM/ This is scaling really nicely. The board design is setup to do up to 450V out on board or drive a second output winding for higher ratio

If you have 600V out of a 160T winding, to get 450V you would simply put a tap at 120T. Completely isolated outputs work the same but instead of a tap, you just have a separate winding for each output. This also points the way to get a low impedance feedback network (Less noise pickup) with a

All this seems easy in writing, but for people like me who are not used to making switching power supplies it would be very kind of you if you could help me (us) with a complete solution when it comes to which toroid core to use and how to wind it. I don't know what your ideas are on how to

For custom voltage supplies that you can do as roll-your-own projects, I have selected a ferrite UU core set that is good to 50W when gapped properly and allows for easy winding off the core (It was doing 92% eff at 30W due to the lower core losses of the ferrite). I am working on a
