Conversion Efficiency 2: An output ripple voltage sometimes changes in capacitor to use, the measurement environment. Especially right attention has to be paid to aluminum electrolytic capacitor,because ESR changes greatly (Vin=141V, Ta=25C) at the time of the low temperature and output voltages increase. 100 Sample Application Circuit 80 12V 1.5A 60 Be sure to use fuse for safety.
