1 Note: use a minimum 2 x 220uF output capacitor. Recommended capacitor is Nichicon CD series, 220uF/35V. If the ambient temperature is less
than -20 O C, use more than 3 of recommended minimum capacitors. When starting into maximum external capacitor, do not simultaneously apply
a Constant Current electronic load set to greater than 0.5 x I
oMAX;
or delay application of full CC load until V
