Case material DERATING＆ DERATING＆EFFICIENCY CURVE Requirement on output load In order to ensure the product operate efficiently and reliably,in addition to a max load(namely full load), a minimum load is specified for this kind of DC/DC converter.Make sure the specified range of input voltage is not exceeded,the minimum output load no less than 10% load.If the actual load is less than the specified minimum load, the output ripple may increase sharply while its efficiency and reliability will reduce greatly.If the actual output power is very small,please add an appropriate resistor as extra loading,or contact our company for other lower output power products. RECOMMENDED CIRCUIT Output Graph In order to obtain better performance for the DC/DC models.it’s recommended that use input and output filters as Fig.1 shown.
