Can a 100khz converter get less hot with paralleled mosfets?

Take a look at the multiphase converter topology. International
Rectifier (www.irf.com) and Texas Instruments (www.ti.com) make parts
for this approach. Basically, you have a separate inductor for each
mosfet so the current is evenly divided among them. The multiphase
part refers to the fact that they are sequenced to be on at different
times so that the magnitude of the ripple current is less.
