Figure 8-2 Start-up By EN. Unless otherwise specified the following conditions apply: VIN
= 24 V, fSW = 500 KHz, L = 8.2 μH, COUT = 2 × 47 μF,
TA = 25°C.
| VIN = 24 V | VOUT = 5 V | IOUT = 2 A |
| VIN = 24 V | VOUT = 5 V | IOUT = 0 A |
| VIN = 24 V | VOUT = 5 V | IOUT = 2 A |
| VIN = 24 V | VOUT = 5 V |
| VIN = 24 V | VOUT = 5 V | IOUT = 2 A |
| VIN = 24 V | VOUT = 5 V | IOUT = 200 mA |
| IOUT: 20% → 80% of 3 A | Slew rate = 100 mA/μs |
| VIN = 24 V | VOUT = 5 V |
