NOTE:
1. The ripple values are measured at 20MHz of bandwidth by using a 12'' twisted pair-wire termin-
ated with 0.1uF & 47uF parallel capacitor under ambient temperature 25℃ at rated input voltage and
rated load;
2. The efficiency values are measured under ambient temperature 25℃ at rated input voltage and rat-
ed load.
