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
channel of output, provided the safe and reliable
operation is ensured, the greatest capacitance of

APPLICATION NOTE
Requirement on output load
Input Voltage
Range
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.
Input Voltage (V)
No parallel connection or plug and play.
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:
Vc-VD-1.0
