APPLICATIONS
The VFA_YMD-5W & VFB_YMD-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
≤2:1);
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.
Note: 1.Models listed with strike-through text have been officially discontinued.
2.*Input voltage can’t exceed this value, or will cause the permanent damage.

APPLICATION NOTE
Recommended Circuit
All the VFA_YMD-5W & VFB_YMD-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).

TYPICAL CHARECTERISTICS
Temperature Derating Graph
(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).
