VWRAS1-SIP Series DC-DC Converter
Rev. 01-2008
- Input current
Application Notes:
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.
- 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).

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.
