Hello:
I think there is a problem in the calculation for the power dissipated in the current sense resistor for the LM5175. This also causes Webench to be unable to find a suitable part. My design is very similar to the example in figure 24 of the data sheet. I need 12 amps output, but over a narrower input voltage range of 10 to 15 volts. The value of Rsense ends up at 4milliohms, but Webench tells me it will dissipate 160 watts! Running through equation 24 gives me 1.6 watts, which is probably correct. Of course, Webench can't find a 4milliohm, 160 watt resistor to put in the BOM...
Regards,
Keith
