1. Min. load shouldn‘t be less than 5ꢀ, otherwise ripple maybe increase
dramatically. Operation under minimum load will not damage the converter,
however, they may not meet all specification listed.
2. Max. Capacitive Load tested at nominal input voltage and constant resistive
load.
3. All specifications measured at Ta=25°C, humidity<75ꢀ, nominal input voltage
and rated output load unless otherwise specified.

Typical application
All the DC/DC converters of this series are tested according to the
recommended circuit (see Fig. 1% before delivery.
It is not allowed to connect modules output in parallel to enlarge the
power.
If it is required to further reduce input and output ripple, properly
increase the input & output of additional capacitors Cin and Cout or
select capacitors of low equivalent impedance provided that the
capacitance is no larger than the max. capacitive load of the product.
