PRODUCTION DATA
This example details the design of a high-frequency switching regulator design using ceramic output capacitors. A few parameters must be known to start the design process. These parameters are typically determined at the system level. For this example, begin with the known parameters listed in Table 8-1.
| DESIGN PARAMETER | EXAMPLE VALUE |
|---|---|
| Output voltage | 3.3 V |
| Output current | 6 A |
| Transient response 1-A load step | ΔVOUT = 5% |
| Input voltage | 12 V nominal, 8 V to 17 V |
| Output voltage ripple | 33 mV p-p |
| Start input voltage (rising VIN) | 6.528 V |
| Stop input voltage (falling VIN) | 6.190 V |
| Switching frequency | 480 kHz |
