Typical board waveforms

The STEVAL-ISA058V1 demonstration board must operate with a wide range of input

voltages. For this reason, the waveforms are reported for the minimum, maximum and

nominal input voltage values.

Figure 6

and Figure 7 show the drain current and the drain voltage waveforms at the

nominal input voltage values, which are 115 VAC and 230 VAC for a maximum load (1 A).

Figure 8

and Figure 9 show the waveforms for the same load condition, but with the

minimum input voltage values (90 VAC) in Figure 8 and the maximum ones (265 VAC) in

Figure 9
