isolated output is required from
a distributed power
system. For these DC-DC converters, You can reduce the
design point of failure and save the development of micro
power supply‘s manpower, material and time costs, also
better ensure product quality stability, protect safety and
reliability of the end of products.
These products apply to where:
1) Input voltage range≤ 2:1;
2) 3KVDC input and output isolation;
3) Regulated and low ripple noise is required.
