EPR-16 – LinkSwitch 2.75 W Charger/Adapter

3 Schematic

Figure 5 – EP-16 Low Cost, 2.75 W LinkSwitch Cell Phone Charger Schematic.

Optional components L2, C6 and R4 may be fitted to the board to improve radiated EMI.

The effect of these components is shown in the “Conducted EMI Results” section of this

document.

Optional component R3 may be fitted in place of L1 in applications where conducted EMI

is filtered externally (e.g. in an embedded system). In this case a 0

Ω resistor or jumper

should be used. In low power applications (less than approximately 1.5 W), a low value

resistor may be used to provide sufficient conducted EMI filtering. A value in the range of

0

Ω to 10 Ω may be used.
