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, and that this product should never be operated under no load! 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, or use our company’s products with a lower rated output power. Recommended testing and application 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 the DC/DC converter, see (Figure 1). KHz *Test ripple and noise by “parallel cable” method. See detailed operation instructions at Testing of Power Converter section, application notes. Note: 1. All specifications measured at TA=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified. 2. See below recommended circuits for more details. TYPICAL CHARACTERISTICS L +Vo1 L Cout Vin 0V1 +Vo2 L DC DC Cin GND Cout 0V2 (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).

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. No parallel connection or plug and play.
