During operation, make sure the DC/DC output end and input end to reduce the noise specified range of input voltage is not exceeded, the and ripple. However, the capacitance of the output minimum output load is not less than 10% of the filter capacitor must be appropriate. If the full load, and that this product should never be capacitance is too big, a startup problem might arise. operated under no load! If the actual output power is For every channel of output, providing that safe and very small, please connect a resistor with proper reliable operation is ensured, the greatest resistance at the output end in parallel to increase capacitance of its filter capacitor is shown in the the load, or use our company’s products with a lower External Capacitor Table. To get an extreme low rated output power. ripple, an “LC” filtering network may be connected to the input and output ends of the DC/DC converter, - Overload protection which may produce a more significant filtering effect. Under normal operating conditions, the output circuit It should also be noted that the inductance and the of these products has no protection against frequency of the “LC” filtering network should be over-current and short-circuits. The simplest method staggered with the DC/DC frequency to avoid mutual is to connect a self-recovery fuse in series at the interference (see figure 1). input end or add a circuit breaker to the circuit.
