See detailed operation instructions at Testing of Power Converter section, application notes. Note: Dual output models unbalanced load: ±5%. APPLICATION NOTE Requirement on output load To ensure this module can operate efficiently and reliably, During operation, the minimum output load is not less than 10% of the full load, and that this product should Operating Temp.(oC) RECOMMENDED CIRCUIT Dual Output L L +Vo Vin Cout DC DC Cin GND -Vo 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 (A/B_XD-W25 Series). Single Output L L +Vo Vin DC DC Cin Cout GND 0V 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). 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 (Figure 1) Dual Output Vin REG REG +Vo REG -Vo REG +Vo 0V DC DC GND 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 Single Output (Table 1). Vin GND Output Voltage Regulation and Over-voltage Protection Circuit The simplest device for output voltage regulation, over-voltage and over-current 0V L Cout REG DC DC 0V (Figure 2) protection is a linear voltage regulator with overheat protection that is connected to the input or output end in series (Figure 2). Overload Protection 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.
