Recommended Circuit
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, see (Figure 1).

However, the capacitance of the output filter
capacitor must be proper. If the capacitance is too
big, a startup problem might arise. For every
100
channel of output, provided the safe and reliable
operation is ensured, the greatest capacitance of
its filter capacitor sees (Table 1). General:

APPLICATION NOTE
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, and that this 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, or use our company’s products with
a lower rated output power.
TRL Terminal
When open or high impedance, the converter work well; When this pin is
‘high’;
the
converter shutdown; It should be note that the input
current should between
5-10mA,exceeding the maximum 20mA will cause permanence damage to the converter. The
value of R can be derived as follows:
