otherwise specified.
2. See recommended circuits below for more details.
Applications:
The VRA3-DIP Series are specially designed for applications where wide range input voltage power supplies are
isolated from the input power supply in a distributed power supply system on a circuit board.
These products apply to:
1) Where the voltage of the input power supply is wide range (voltage range: 2:1);
2) Where isolation is necessary between input and output (Isolation Voltage = 1500 Vdc)
3) Where the regulation of the output voltage and the output ripple noise are demanding.

Requirement on Output Load
2.54
To ensure this module operates efficiently and
2 x 2.54
reliably, a minimum load is specified for this

kind of DC/DC converter in addition to a
maximum load (namely full load). During

operation, make sure the specified range of
input voltage is not exceeded, the minimum

the output ripple of this type of DC/DC converter
will increase drastically and at the same time
efficiency & reliability of the circuit will decrease
deeply .If the actual output power from the load
in your circuit is very small, please connect a
resistor with proper resistance at the output end
to in parallel to increase the load, or use our
company’s other products with a lower rated
output power.
The products cannot be used in parallel and

Application Note
Recommended circuit
All the VRA3-DIP Series have been tested according to the following
recommended testing circuit before leaving factory. This series should be
tested under load. Never be tested under no load (see figures 1 & 2). 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 (external capacitor table). If you want
to use the products in high EMI, please choose our metal packaged
products.

Input Current
When it is used in unregulated power supply, be sure that the fluctuating
range of the power supply and the rippled voltage do not exceed the
module standard. Input current of power supply should afford the startup
current of this kind of DC/DC module (see figure 2).
