APPLICATION NOTE
1) CS Pin
By connecting a low ESR capacitor between this terminal and the pin-7(Figure 1), the output
ripple and noise may be further improved. Generally, the capacitance is no greater than 47uF.
2) Requirement on Output Load
To ensure this module can operate efficiently and reliably, During operation, the minimum
output load is not less than 10% of the full load, If the actual load is less than
the specified
minimum load, the output ripple may increase sharply. 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.

If you want to further decrease the input/output ripple, you can increase capacitance properly
or choose capacitors with low ESR (Figure 1).

4) Input current
When the environment temperature is higher than 71°C, the product
output power should be less than 60% of the rated power.
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

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
Thisseries 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 backward compatible with Sn/Pb soldering systems.
