WRE_S - 3WR2 & WRF_S - 3WR2 Series
Design Reference
1. Recommended circuit
All the DC/DC converters of this series are tested according to the recommended circuit (see Fig. 2) before delivery.
If a further decrease of the input and output ripple is required, properly increase the input & output of additional capacitors Cin1, Cin2, Cs
and Cout; or select capacitors of low equivalent impedance like series capacitor, etc. Cs is used to reduce ripple. No need to add Cs, if
ripple meets the demand .Appropriate filter capacitance shall be chosen, start-up problems may be caused if the capacitance is too
large. For each output circuit, under the condition of safe and reliable operation, the max. capacity of its filter capacitor should be lower
than the max. capacitive load.

Notes:
① Part ① in Fig. 3 is used for EMS test while part ② is used for EMI filtering; and parts ① and ② may be selected based on needs.
② VC is the voltage of the Ctrl end relative to the GND of the input grounding; VD is the positive-going conduction pressure drop of D1; IC is the current flows
into the Ctrl end and its value is generally 5-10mA, see Fig. 3-③ for the peripheral circuit of Ctrl end;
③ If there is no recommended parameters, no external component is required.
3. Ctrl end
The modules are of normal output when the Ctrl end is suspended or of high resistance; the modules turn off when connecting with high
level (relative to the input grounding); notice that the current flows into the pin shall be 5 - 10mA, the modules will be permanently damaged
if the current exceeds its max. value (20mA in general).
The value of R can be derived as follows:
VC -VD -1.0
R =
-300
IC
For Detailed parameter, please refer to EMC solution-recommended circuit in this manual.
4. Input current
When the electricity is provided by the unstable power supply, please make sure that the range of the output voltage fluctuation and the
ripple voltage of the power supply do not exceed the indicators of the modules. Input current of power supply should afford the flash startup
current of this kind of DC/DC module(see Fig. 5).
Generally: Vin= 5V series Iave =1315mA
Vin=12V series lave =631mA
Vin=24V series lave =303mA
Vin=48V series lave =158mA

5. Output load requirements
When using, the minimum load of the module output should not be less than 5% of the nominal load.In order to meet the performance
parameters of this datasheet, please connect a 5% dummy load in parallel at the output end, the dummy load is generally a resistor, please
note that the resistor needs to be used in derating.
