9.2.3 Application Curves
Unless otherwise specified the following conditions apply: VIN = 12 V, TA = 25°C. The circuit is shown in Figure 17, with the appropriate BOM from Table 4.
| VOUT = 5 V | 400 kHz | |
| VOUT = 5 V |
| VIN = 12 V | VOUT = 5 V | |
| IOUT = 0 A to 4 A | tf = tr = 4 µs | |
| VOUT = 5 V | 400 kHz | |
| VIN = 13.5 V | VOUT = 5 V | IOUT = 4 A | |
| VIN = 12 V | VOUT = 5 V | |
| tf = tr = 2 µs | IOUT = 2 A to 4 A | |
