The input - All of the VWQBS2-SIP Series have been tested current of the power supply must be sufficient according to the following recommended testing to the startup current (Ip) of the DC/DC module circuit before leaving the factory. This series should (Figure 2) be tested under load(Figure 1). If you want to further decrease the input/output ripple, you can increase Input Current(A) capacitance properly or choose capacitors with low ESR. However, the capacitance should not be too high(Table 2). Ip Input Voltage Range Table 2 Input Voltage (V) Vout Cout (Max) 3.3 820μF 5 680μF 9 470μF In order to ensure the product operates 12 330μF efficiently and reliably, make sure the specified range 15 220μF of input voltage is not exceeded. - Output Load No parallel connection or plug and play. Figure 1 Temperature Derating Graph Operating Temp.( C ) - NC Terminals Unless otherwise specified, NC terminals of all series are used for converter's interior circuit connection, and are not allowed connection of any external circuit.; - 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.
