PRODUCTION DATA.
This example details the design of a high frequency switching regulator design using ceramic output capacitors. A few parameters must be known in order to start the design process. These parameters are typically determined at the system level. For this example, we start with the following known parameters:
| DESIGN PARAMETER | EXAMPLE VALUE |
|---|---|
| Output voltage | 3.3 V |
| Output current | 3 A |
| Transient response 1-A load step | ΔVout = 5% |
| Input voltage | 5-V nominal, 4.5 V to 6.3 V |
| Output voltage ripple | 33 mV p-p |
| Start input voltage (rising Vin) | 4.425 V |
| Stop input voltage (falling Vin) | 4.234 V |
| Switching frequency | 480 kHz |
