NOTE :
1. Measured From High Line to Low Line
2. Measured From Full Load to 10% Load
3. Maximum case temperature under any operating condition should
not be exceeded 100℃.
4. For asymmetric loading, Both channels must be at 25% load or more
5. The EC3SAW series meet EN55022 Class A & Class B with external C-
L filter before the input pins to the converter.(see application note )
