Notes:
1. Values and configurations for these
components can be derived from Table 18
or from “AN45: Design Guide for the
Si3210/15/16 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.
