This series should be tested under load(Figure 1). If you want to further decrease the input/output ripple, you can increase capacitance properly or choose capacitors with low ESR. However, the capacitance should not be too high(Table 2). - Input current While using the unstable power source, please ensure the output voltage and ripple voltage do not exceed indexes of the converter. The preceding power source must be able to provide for converter sufficient starting current lp. (Figure 2) Input Current(A) Ip Table 2 Vout 5 9 12 15 24 Cout (Max) 330 220 100 47 22 Input Voltage Range Input Voltage (V) No parallel connection or plug and play. Figure 1 Temperature Derating Graph Operating Temp.( C ) - CTRL Terminal When open or high impedance, the converter will work well; When this pin is `high'; the converter will shutdown; It should be noted that the input current should remain between 5-10mA,exceeding the maximum 20mA will cause permanent damage to the converter.
