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.

- 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.
