Note:

1.

External electrolytic capacitor are required to models when AC input, more details refer to typical applications.

2.

Ripple and Noise were measured by the method of anear measure (more details refer to the anear measure).

3.

All specifications measured at Ta=25

°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified.

4.

In this datasheet, all the test methods of indications are based on corporate standards.
