Benefits of match controller and NexFETs
TPS40305 Advantages
  • Lower dead times improves efficiency
  • Strong gate drivers reduces switching losses
  • Higher gate driver voltage reduces Rdson
NexFET Advantages
  • 3-4% higher efficiency at mid to heavy loads over other MOSFETs
  • Allows 2x switching frequency for overall smaller solution size
