VWRAS1-SIP Series DC-DC Converter

Application Notes:

- All of the VWRAS1-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 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.

- 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.
