max votlage on TEA2208

[febat]

Dear All,

for a new project of a power supply at 30Vcc and up 15A, I'm evaluation to use TEA2208 as active full-bridge controller.

The archietecture is very simple:
1) toroidal transformer from 230Vac to 31Vac (tolerance -15% / +10%)
2) bridge
3) dc-dc to have 30Vcc.

So I would like to use the TEA2208 as ative full bridge contoller, but I think it's not possible because Vcc max voltage il 14V, instead in my project the Vout is 31Vcc...

Solutions?

Thank You and Best Regards

I don't understand what means Vth...

I noted VL and VR is hundreds Volt... but I can't have the DC Vout about 32V... it's very strange...

Someone clarify me...

Best Regards
Federico

Perhaps you misunderstand this VCC define which is no problem for your case ,but  you should consider about the VTH max is 32V but in your application is 31V.
