I am going to change my recommendation to the TPS43060 because it uses a higher voltage gate drive. This allows use of a bigger FET with lower RDson to further reduce power loss. The key for high power designs is to reduce power loss as much as possible to make sure the components are not operating at too high of a temperature. As such lower switching is preferred to reduce switching losses and it may also be needed to use two FETs in parallel. The TPS43060EVM-199 can be used to evaluate your design without parallel FETs.
