PRODUCTION DATA
This example details the design of a triple-synchronous step-down converter. A few parameters must be known to start the design process. These parameters are typically determined at the system level. For this example, start with the following known parameters shown in Table 9-1.
| PARAMETER | VALUE |
|---|---|
| Vout1 | 1.2 V |
| Iout1 | 3 A |
| Vout2 | 1.8 V |
| Iout2 | 1 A |
| Vout3 | 3.3 V |
| Iout3 | 1 A |
| Buck1 transient response 1-A load step | ±5% |
| Buck2, buck3 transient response 0.5-A load step | ±5% |
| Input voltage | 12 V normal, 4.5 to 18 V |
| Output voltage ripple | ±1% |
| Switching frequency | 600 kHz |
