Recommended FETs for TPS40305
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
Efficieny VS Load Current
Vin=12V, VOUT=1.2V Efficiency with TI NexFETs Controllers
Vin: 5V, Vout=1.2V Efficiency >90%, 1-20A (pk
~95%)
Vin: 12V, Vout=1.2V Efficiency =92% @15A
