Note:
1. Recommend to use module with more than 5% load, if not, the ripple of the
product may exceeds the specification, but does not The maximum capacitive
load offered were tested at nominal input voltage and full load;
2. Unless otherwise specified, parameters in this datasheet were measured under
the conditions of Ta = 25°C, humidity <75%RH with nominal input voltage and
rated output load;
3. All index testing methods in this datasheet are based on our Company’s
corporate standards;
4. The performance parameters of the product models listed in this manual are
as above, but some parameters of non-standard model products may exceed
the requirements mentioned above. Please contact our technicians directly
for specific information;
5. We can provide product customization service;
6. Specifications are subject to change without prior notice.

DC-DC Converter
Typical application
All the DC/DC converters of this series are tested according to the
recommended circuit (see Fig. 2) before delivery.
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 pro-
duct.
