Notes:

1.

All parameter are typical at 25 °C, nominal input voltage and full load specified, unless otherwise noted.

2.

Capacitive load tested by minimal input voltage and constant resistive load.

3.

An external filter is required to meet EFT standard IEC 61000-4-4 and IEC 61000-4-5. (see Figue 4)

Figure 2 Measure circuit input ripple current
