APPLICATIONS
The D-XNS-2W series are specially designed for
applications where a group of polar 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 fixed
(voltage variation ≤±10%);
2) where isolation is necessary between input and
output (isolation voltage ≤1000VDC);
3) where the regulation of the output voltage and the
output ripple noise are not demanded.
Such as: purely digital circuits,ordinary low
frequency analog circuits,and 1GBT power device
driving circuits.
