The WRB-YES-1W&WRB-YES-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:

TYPICAL APPLICATIONS

Cin:

5V,12V 100PF

24V,48V 10uF

Cout: 47PF(typ.)

Lin: 4.7PH ~120PH

Lout: 2.2PH ~10PH

2) Input current

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.

General: Ip≤1.4*Iin-max

When the environment temperature is higher than 71℃, the

product output power should be less then 60% of the rated power.

No parallel connection or plug and play.

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.
