See detailed operation instructions at Testing of Power Converter section, application notes. Operating Temp.(oC) APPLICATION NOTE 1) Requirement on output load To ensure this module can operate efficiently and reliably, During operation, the RECOMMENDED CIRCUIT minimum output load could not be less than 10% of the full load. If the actual output power is very small, please connect a resistor with proper resistance at the output end in L L +Vo Vin DC DC Cin Cout GND 0V parallel to increase the load. (Figure 1) 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 the DC/DC converter, see (Figure 1). It should also be noted that the inductance and the frequency of the “LC” filtering network Vin +Vo REG DC DC GND 0V 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 application field. REG Vin startup problem might arise. It’s not recommended to connect any external capacitor in the GND +Vo DC DC 0V (Figure 2) 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 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. 5) No parallel connection or plug and play The copyright and authority for the interpretation of the products are reserved by MORNSUN Specifications subject to change without notice.
