Figure 25. Input Voltage Surges Protection
Electrical Over Stress Ruggedness
The VIPer may be submitted to electrical over-stress, caused by violent input voltage surges or lightning.
Following the Layout Considerations is sufficient to prevent catastrophic damages most of the time.
However in some cases, the voltage surges coupled through the transformer auxiliary winding can
exceed the V
protection circuitry which could be damaged by the strong discharge current of the V
The simple RC filter shown in (see Figure 25) page 17 can be implemented to improve the application
immunity to such surges.
