## MOSFET Power Losses
### Conduction Loss
**P_cond = Rds(on) x I_D^2**
### Switching Loss
**P_sw = 0.5 x V_DS x I_D x (t_rise + t_fall) x f_sw**
Total loss is the sum. Conduction loss dominates at low frequencies; switching loss dominates at high frequencies.

Esempio Risolto
MOSFET with 50 mohm Rds(on), 5 A load, switching 12 V at 100 kHz with 50 ns transitions.
- Conduction = 0.05 x 25 = 1.25 W
- Switching = 0.5 x 12 x 5 x 50e-9 x 100000 = 0.15 W
- Total = 1.25 + 0.15 = 1.40 W
