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 dB

µV 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.
