Notes:
1. Values and configurations for these
components can be derived from Table 19 or
from “AN45: Design Guide for the Si3210 DC-
DC Converter”.
2. Only one component per system needed.
3. All circuit grounds should have a single-point
connection to the ground plane.
4. Optional components to improve idle channel
noise
