Operating Temp.(oC) TYPICAL CHARACTERISTICS Requirement on output load To ensure this module can operate efficiently and reliably, During operation, the RECOMMENDED CIRCUIT 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 L L +Vo Vin DC DC Cin Cout GND 0V connect a resistor with proper resistance at the output end in parallel to increase the load. (Figure 1) 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 Vin +Vo REG DC DC GND 0V 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 capacitor in the application field. REG Vin too big, a startup problem might arise. It’s not recommended to connect any external GND +Vo DC DC 0V (Figure 2) 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). Overload Protection Under normal operat ing 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.
