Note: 1. External electrolytic capacitors are required to modules, more details refer to typical applications.

2. Ripple and Noise measuring refer to

“ripple and noise measure figure”.

3. All specifications were measured at Ta=25

°C, humidity<75%, nominal input voltage (115VAC or 230VAC)and rated output load unless otherwise specified.

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