APPLICATIONS
The URA_D-5W & URB_D-5W Series are
specially designed for applications where a
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
≤4:1);
2) Where isolation is necessary between
input and output (Isolation voltage
≤
1500VDC);
3) Where the regulation of the output voltage
and the output ripple noise are demanded.

APPLICATION NOTE
Recommended Circuit
All the URA_D-5W & URB_D-5W 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 Figure 1).

If you want to further decrease the output ripple,
you can increase capacitance properly or choose
capacitors with low ESR. However, the
capacitance should not be too high.(Table 1).
