Figure 9-17 Efficiency vs IOUT and VIN
| VIN step to 48 V | 1.5-Ω Load |
| VIN = 48 V | 1.5-Ω Load |
| VIN = 48 V |
| VIN = 48 V |
| IOUT = 4 A |
| VIN = 48 V | FSW = 350 kHz | IOUT = 8 A |
| VIN = 48 V | VOUT = 12 V | 6-A resistive load | |
| VIN = 48 V | IOUT = 8 A |
| 1.5-Ω Load |
| VIN = 48 V | 1.5-Ω Load |
| VIN = 48 V |
| VIN = 48 V | IOUT = 8 A |
| VIN = 48 V | IOUT = 0 A |
| VIN = 48 V | IOUT = 8 A |
| VIN = 48 V | VOUT = 12 V | 6-A resistive load | |
