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 ≤ 1000VDC);
3) Where isolation is necessary between Vout1 and Vout2
(Isolation Voltage ≤ 1000VDC);

If you want to
further decrease
the
input/output ripple, you can
increase capacitance properly
or choose capacitors with low ESR (Figure 1).
However, the capacitance of the output filter capacitor must be proper. If the capacitance is too

Note:
1. The load shouldn't be less than 10%, otherwise ripple will increase dramatically.
2. Operation under 10% load will not damage the converter; However, they may not meet all specification listed.
3. All specifications measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified.
4. In this datasheet, all the test methods of indications are based on corporate standards.
5. Only typical models listed, other models may be different, please contact our technical person for more details.
RoHS COMPLIANT INFORMATION
This series is compatible with RoHS soldering systems with a peak wave solder temperature
of 300°C for 10 seconds.
