VWRAS3-SIP Series DC-DC Converter
Rev. 07-2007
- Input current
Application Notes:
Nominal input voltage range. The input
current of the power supply must be sufficient
to the startup current (Ip) of the DC/DC module
(Figure 2)
- All of the VWRAS3-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).

In order to ensure the product operates
efficiently and reliably, make sure the specified range
of input voltage is not exceeded.
No parallel connection or plug and play.

- 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.
