Transformer design

Posted by: joangusi on 02/08/2011

I am designing T8 isolated led driver similar to DER-256.

My specs are:

Vin: 90-265Vac
Vout: 92V, 0,12A

I have Vf max=3,8V and I conect 24 leds in serie.

I have used PIXIs Designer software but core type: EER2510 is not defined and I can not use it to get the transformer parameters.

I need maximum height transformer: 10mm or lower height.

Can you help me?

Thanks,

What's the problem? Just use another type core applicable for power and horizontal bobbin with it. For example EE19

I need to use this type of core due to the transformer height must be lower than 10mm. It is to be used into T8 tube.

I don't have enough space to use EE19. The core must be as smaller as possible.

Thanks,
