9.2.2 Application Curves
Unless otherwise specified, the following conditions apply: VIN = 24 V, TA = 25°C. Figure 32 shows the circuit with the appropriate BOM from Table 5.
| LMR36520A | VOUT = 3.3 V | 400 kHz |
| LMR36520A | VOUT = 5 V | 400 kHz |
| LMR36520A | VOUT = 12 V | 400 kHz |
| VOUT = 5 V | 400 kHz |
| VOUT = 3.3 V | IOUT = 0 A |
| VIN = 24 V | VOUT = 3.3 V | ILOAD = 2 A |
| VOUT = 3.3 V | 400 kHz | ILOAD = 0.5 A - 2 A |
| Slew Rate = 1 A/µs |
| VIN = 24 V | VOUT = 5 V | ILOAD = 0 A |
| LMR36520A | VOUT = 3.3 V | 400 kHz |
| LMR36520A | VOUT = 5 V | 400 kHz |
| LMR36520A | VOUT = 12 V | 400 kHz |
| VOUT = 12 V | 400 kHz |
| VOUT = 3.3 V | RFBT = 100 kΩ |
| VIN = 24 V | VOUT = 3.3 V | ILOAD = 2 A |
| VOUT = 5 V | 400 kHz | ILOAD = 0.5 A - 2 A |
| Slew Rate = 1 A/µs |
| VIN = 24 V | VOUT = 5 V | ILOAD = 1 A |
