Balancing Efficiency andCost
Optymalizacja fur efficiency of ten involves selecting MOSFET s with low Rds (on) and fast change g capabilities. However, these devices tend to be more lossive. Conversele, cost- effective MOSFET may have hiper conduction and change g losses, which chich can reduce overall system efficiency.
Projektanci muszą oceniać te zastosowania poziomów power, częstotliwość zmian, i thermal management to determinate thee bett trade- offs. In some case, using multiple MOSFET in parallem can improwizuj wydajność bez konieczności znaczącego wzrostu kosztów.
