-All of the VWQAS2-SIP Series have been tested according to the following recommended testing circuit before leaving the factory.
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 1).
NCs 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
2.
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.
