PRODUCTION DATA
This example details the design of a high-frequency switching regulator using ceramic output capacitors. To start the design process, it is necessary to know a few parameters. Determination of these parameters typically occurs at the system level. For this example, we start with the following known parameters:
| DESIGN PARAMETER | EXAMPLE VALUE |
|---|---|
| Output voltage | 1.8 V |
| Transient response, 1-A to 2-A load step | ΔV(out) = 5% |
| Maximum output current | 4 A |
| Input voltage | 5 V nominal, 3 V to 6 V |
| Output-voltage ripple | < 30 mV p-p |
| Switching frequency (f(SW)) | 1000 kHz |
