EPR-16 – LinkSwitch 2.75 W Charger/Adapter
11.5 EMI Performance
No change in conducted EMI performance was measured. The results of the LNK520P
and modified EP-16 were the same as the original EP-16 design, as shown in Figures 24
and 25.
However, the optimized switching characteristics of LNK520P produced a significant
reduction in radiated EMI. Figure 34 provides a comparison of quasi-peak radiated
emissions with the original EP-16 (LNK501P) and modified EP-16 (LNK520P) designs.
A 6 dBµV to 12 dBµV reduction is shown with the LNK520P device. The results are
shown as a comparative reference. Actual radiated emissions levels will vary according
to radiated test setup and measurement configurations.
