Also, this product should never be operated under no load conditions. If the actual output power is too small, please connect a resistor with proper resistance at the output end in parallel to increase the load. - 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). FIGURE 2 Vin GND REG +Vout DC DC 0V REG - 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 to add a circuit breaker to the circuit. - 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). Vin GND +Vout DC DC 0V TYPICAL CHARACTERISTICS FIGURE 1 +Vin Cin L L +Vout Cout -Vin DC DC -Vout 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 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.
