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. Dual output models unbalanced load: ±0.5%. Under normal operating conditions, the output circuit of these products has no protection against overload. The simplest method is to connect a self-recovery fuse in series at the input end or add a circuit breaker to the circuit. Recommended testing and application circuit If you want to further decrease the input/output ripple, “LC” an filtering network be DC/DC converter, see (Figure 1). Dual Output L L +Vo Vin Cout DC DC Cin 0V L Cout GND -Vo Single Output L L TYPICAL CHARACTERISTICS may connected to the input and output ends of the +Vo Vin Cout DC DC Cin GND 0V (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 Ambient Temperature ( C ) arise. For every channel of output, provided the safe and reliable operation is ensured, the OUTLINE DIMENSIONS & PIN CONNECTIONS greatest capacitance of its filter capacitor sees (Table 1).

If the actual output power is very small, please connect a resistor DC DC 0V (Figure 2) 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 (A_D -1W/B_D-1Wseries).
