RECOMMENDED CIRCUIT
APPLICATION NOTE
1) Requirement on output load
In order to ensure the product operate efficiently and reliably, in addition to a max load (namely full
load), a minimum load is specified for this kind of DC/DC converter. Make sure the specified range of
input voltage is not exceeded, the minimum output load no less than 10% load. If the actual load is less
than the specified minimum load, the output ripple may increase sharply while its efficiency and reliability
will reduce greatly. If the actual output power is very small, please add an appropriate resistor as extra
loading, or contact our company for other lower output power products.
2) Recommended Circuit
All the WRA_ZT-1W5
& WRB_ZT-1W5 series have been tested according to the following
recommended testing circuit before leaving factory. This series should be tested under load (see Figure 1).
If you want to further decrease the input/output ripple, you can increase capacitance properly or choose
capacitors with low ESR. 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 maximum capacitance of its filter capacitor sees (Table 1). General:
Cin: 10µF~47µF
Cout: 10µF/100mA
3) Input Current
When it is used in unregulated power supply, be sure that the fluctuating range of the power supply
and the rippled voltage do not exceed the module standard. Input current of power supply should afford the
flash startup current of this kind of DC/DC module (Figure 2)
General: Ip ≤1.6*Iin-max
4) 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. Capacitor MAX load tested at input voltage range and full load.
4. All specifications measured at Ta=25℃, humidity<75%, nominal input voltage and rated output load unless otherwise specified.
5. Only typical models listed, other models may be different, please contact our technical person for more details.
6. In this datasheet, all the test methods of indications are based on corporate standards.
RoHS COMPLIANT INFORMATION
This series is compatible with RoHS soldering systems with a peak wave solder temperature of 300°C
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
