SSL5301DB1233 230 V 36 W LED driver demo board
12. Errata
12.1 Converter does not start when mains protective earth is connected
When the mains protective earth is connected, the converter does not start up. The
present SSL5301DB1233 demo board, the Protective Earth (PE) is not connected so no
start-up issues occur.
When PE is connected, connect the primary ground side of the Y-capacitor to the negative
node of the bridge rectifier (see Figure 11
).
12.2 EMI performance shows increased peaking at 20 MHz with PE
connected
When the mains Protective Earth (PE) is connected, the EMI performance decreases at
20 MHz. The performance decreasing is not an issue in the present SSL5301DB1233
demo board because PE is not connected.
