Figure 13. Si3210/Si3210M Typical Application Circuit Using Discrete Components
Notes:
1. Values and configurations for these compo-
nents 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.
5. The trace resistance between R6 and C26
should equal the trace resistance between R 7
and C26.
6. Pin numbers for TSSOP shown.
