DC/DC converter
INPUT FILTERING
If you want to further decrease the input/output ripple, an “LC”
filtering network may be connected to the input and output ends
of the DC/DC converter as shown in Figure 1.
TYPICAL CHARACTERISTICS
The inductance and frequency of the “LC” filtering network
should be staggered with the DC/DC frequency to avoid mutual
interference. 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 greatest capacitance
of its filter capacitor sees.
RECOMMENDED REFLOW SOLDERING PROFILE
To ensure this module can operate efficiently and reliably during
operation, the minimum output load is not less than 10% of the
full load and the product should never be operated under no
load. If the actual output power is very small, please connect a
resistor with proper resistance at the output end in parallel to
increase the load.
It’s not recommended to connect any external capacitor in the
application field with less than 0.5 watt output.
