Actually, the purpose of the secondary linear regulator is more to hide the "approximations" of the initial dc-dc conversion phase (which will be hard to tune perfectly due to the wide output range, as you said) rather than smoothing the switching noise, you're right. I'll use some ferrite and caps anyway, but the switching noise is not my main concern. I don't design medical devices (hopefully). The PCB will be 2 layers. I'll try do lay it out carefully. | |
