See detailed operation instructions at Testing of Power Converter section, application notes. APPLICATION NOTE RECOMMENDED CIRCUIT 1) Requirement on output load To ensure this module can operate efficiently and reliably, a minimum load is specified for this kind of DC/DC converter in addition to a maximum load (namely full load). During operation, make sure the specified range of input voltage is not exceeded, the minimum output load could not be less than 10% of the full load. If the actual output L +Vo1 L Cout Vin 0V1 +Vo2 L DC DC Cin GND Cout 0V2 power is very small, please connect a resistor with proper resistance at the output end (Figure 1) in parallel to increase the load, or use our company’s products with a lower rated output power. Vo1 2) Recommended testing and application circuit If you want to further decrease the input/output ripple, an “LC” filtering network may Vin REG 0V1 DC DC Vo2 GND 0V2 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. +Vo REG +Vo Vin 0V DC DC 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, REG GND 0V provided the safe and reliable operation is ensured, the greatest capacitance of its filter (Figure 2) capacitor sees (Table 1). 3) Output Voltage Regulation and Over-voltage Protection Circuit The simplest device for output voltage regulation, over-voltage and over-current protection is a linear voltage regulator with overheat protection that is connected to the input or output end in series (Figure 2). 4) 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.
