APPLICATION NOTE
Requirement on output load
To ensure this module can operate efficiently and reliably, a minimum load is specified for
this kind of DC/DC converter in addition to a maximum load (namely full load). During
operation, make sure the specified range of input voltage is not exceeded, the minimum
output load is not less than 10% of the full load, that this product should never be
operated under no load!
