Hi,

I'd like to get the WEBENCH simulation result of LM22679 with following conditions,

Vin=35V Vout=26.5V Iout=5A

But I couldn't get the result and got the comment "Output voltage not supported".

is there any problem for the condition?

Thanks

For LM22679, the internal compensation is optimized for output voltages less than 5 V. That is why Webench does not support higher output voltages.

Hi, John

Thank you for your comment.

But according to D/S, we can use 5.0V fixed output option for an output voltage greater than 5.0V.

Is it possible to support higher voltage simulation with LM22679-5.0 on WEBENCH?

Thanks
