PART NUMBER: VWRAT2  
DESCRIPTION: dc-dc converter  
- 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 VWRAT2-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).

In order to ensure the product operates  
efficiently and reliably, make sure the specified range  
of input voltage is not exceeded.  
-Vout  
- Recommended circuit  
No parallel connection or plug and play.  
It is best to test with full load and not to test without load. To  
further reduce output ripple, you may increase the external  
capacitor, choose a capacitor with low ESR, or add external  
inductor to the circuit as shown above.  
- 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.
