Transformer for a LM2588 Simple Switcher

Nick Trollope

I am designing a simple 12VDC - 260VDC (20mA) switcher and I am stuck for a (UK) source for a 'T1' - 1:14 with a 135uH primary.

Or, a design calculator for ring ferrite cores?

Thanks in advance

Hi Nick,

I am not sure if you can get access to US manufacturer. But normally Wurth Elektronik or Payton or Pulse transformer has a number selection of transformer.
If you want to wind yourself maybe this link might help but it only use the E core

Check with the core manufacturer how many windings you need to get your 135uH and having a saturation current of 1A or so.

Thanks
