Application
The
VRB_MP-8W
Series
is
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
range is wide (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 dem anded.

Recommended Circuit
All the VRB_MP-8W 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 CHARACTERISTICS
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
can’t exceed the maximum capacitor load in the list.
