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. 2.Recommended circuit If you want to further decrease the input/output ripple, an “LC ” filtering network may be connected to the input and output ends of theDC/DC converter, see(Figure 1). It should also be noted that the inductance and the frequency of the “LC ” filtering network should be staggered with the DC/DC frequency to avoid mutual interference. 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 its filter capacitor sees (Table 1) EXTERNAL CAPACITOR TABLE (TABLE 1) Vin (VDC) Cin (μF) Vout (VDC) Cout (μF) 5 4.7 ±5 4.7 12 2.2 ±9 2.2 24 0.47 ±12 1 - - ±15 0.47 3.Overload Protection Under normal operating conditions, the output circuit of these products has no protection against over-current and short-circuits. The simplest method is to connect a self-recovery fuse in series at the input end or add a circuit breaker to the circuit. 4.Input Over-voltage Protection Circuit The simplest device for input over-voltage protection is a linear voltage regulator with overheat protection that is connected to the input end in series (Figure 2). When the environment temperature is higher than 71°C, the product output power should be less then 60% of the rated power. No parallel connection or plug and play. Use dual output simultaneously, forbid opening output pin (0V) to use as single output. APPLICATION NOTE （Figure 1)
