Line regulation

For this test the output power is kept at the peak value (2.2 W) while the line voltage is

slowly increased from 85 Vac to 265 Vac. The board has a line regulation of +0.9%.

Figure 37.

Load regulation

As the 5 V output is obtained by a linear regulator, the load regulation measurements have

been performed only on 20 V output by changing its load from 10 mA to full load 100 mA.

The input voltage is kept at the nominal value of 230 Vac.

The board has a load regulation of +0.9%.
