DESCRIPTION
The WRA_YS-2W&WRB_YS-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
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.

APPLICATION NOTE
SIZE Graph
1) Recommended circuit
If you want to further decrease the input/output ripple, an "LC" filtering network may be connected to the input and output
ends of the DC/DC converter, see (Figure 1). Lin However, the capacitance of the output filter capacitor must be proper. If
the capacitance is too big, a startup problem might arise. For every channel of output, provided the safe and reliable
operation is ensured, the greatest capacitance of its filter capacitor sees (Table 1). General:
Cin:
5V,12V 100PF
24V,48V 10uF
Cout: 47PF(typ.)
Lin:
4.7PH ~120PH
Lout:2.2PH ~10PH
Cs:
10uF ~ 22uF
2) CTRL Terminal
When open or high impedance,the converter work well; When this pin is "high"; the converter shutdown; It should be note
that the input current (Ic) should between 5-10mA, exceeding the maximum 20mA will cause permanence damage to the
converter. The value of R Can be derived as follows :
3) Input current
EXTERNAL CAPACITOR TABLE (TABLE 1)
While using unstable power source, please ensure the output voltage and ripple voltage do not exceed indexes of the
converter. The preceding power source must be able to provide for converter sufficient starting current Ip (Figure 2).

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℃, humidity<75%, nominal input voltage and rated output load unless otherwise specified.
4.In this data sheet, 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℃ for 10 seconds.
The pin termination finish on the SIP package type is Tin Plate, Hot Dipped over Matte Tin
with Nickel Preplate. The DIP types are Matte Tin over Nickel Preplate. Both types in this
series are backward compatible with Sn/Pb soldering systems.
