- Input current
Application Notes:
Nominal input voltage range. The input
- All of the VWRBT1-SMT Series have been tested
current of the power supply must be sufficient
according to the following recommended testing
to the startup current (Ip) of the DC/DC module
circuit before leaving the factory. This series should
(Figure 2)
be tested under load (Figure 1). If you want to
Figure 2
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
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.
General:
Cin: 12V 100μF
24V 10μF or 22μF
Cout:100μF(typ)
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.
