LM5148: Input 75V and Iout 10A solution

Hi Brian,

For the 12V/8.3A design, take a look at the LM5146 EVM, https://www.ti.com/tool/LM5146-Q1-EVM12V. This EVM is 12V/8A at Fsw = 400kHz using 100V MOSFETs. Note that an 80V controller may be somewhat tight for a 75V max Vin, hence the recommendation for a 100V controller. Another advantage is the LM5146 drives standard-logic FETs.

For the 5V/10A design, you may want to check design circuit #1 in the LM5146 datasheet, which is 5V/12A/3000kHz: https://www.ti.com/lit/ds/symlink/lm5146.pdf#page=36.

Regards,

Tim
