Other Parts Discussed in Thread: LM5118

Hello,

I simulated LM5118 by below conditions by WEBENCH.

But webench couldn't simulate due to "Can't find suitable FET for the design".

Vin(min) 12V

Vin(max) 60V

Vout 28V

Iout 4A

I thoght that LM5118 is only one device for this solution due to LM5118 is back boost with wide Vin range.

Can't operate LM5118 above condition ?

If yes, please kindly let me know the refference design. and why webench can't simulate.

If no, could you pleaes kindly let me know other device which can operate this condition, if there is.

Best Regards,

LM5118 might not be suitible for such a high power converter. Please refer 4-swtch design at http://www.ti.com/tool/lm5118-4-swxevm
