Notes: 1. At full load, nominal AC input voltage, 25°C, 20 MHz bandwidth oscilloscope, output terminated with 0.1 µF and 10 µF capacitors to ground. 

2. CoC Tier 2 compliant. 

3. Average efficiency is measured at 25%, 50%, 75%, and 100% load. 

4. All specifications are measured at Ta=25°C, nominal input voltage, and 75% rated output load unless otherwise specified.
