3.Recommend Circuit DC/DC test circuit: If you want to further decrease input& output ripple, the capacitance of external capacitor can be increased properly, but the maximum capacitance of the filter capacitor should be less than the maximum capacitive load, otherwise it will make it difficult to turn-on the module. Normal Recommend: Ci:100uF (5V&12V) / 10uF (24V&48V) Li:4.7uH～120uH CS:10uF～22uF Co:100uF (Typ.) Lo;2.2uH～10uH C1:47nF/100V Single Output Positive Negative Dual Output Photo 13 4.CTRL Terminal Suspended or high resistance, output of module runs normally; Connect to high...
