Note:
1. Operation under minimum load will not damage the converter; However, they
may not meet all specification listed, and that will reduce the life of product.
2. All specifications measured at Ta=25°C, humidity<75%, nominal input voltage
and rated output load unless otherwise specified.
3. In this datasheet, all the test methods of indications are based on corporate
standards.
