However, the Temperature Derating Graph capacitance of the output filter capacitor must proper. If the capacitance is too big, a startup problem might arise. For every channel of output, providing operation is the safe ensured, and the reliable greatest capacitance of its filter capacitor refer to the external capacitor table (table1).

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!
