-All of the VWRAS1-SMT 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).

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.
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 1)
