During operation, make sure the specified range of input voltage is not exceeded, over-voltage and over-current protection is a linear the minimum output load is not less than 10% of the full load, and that this product voltage regulator with overheat protection that is should never be operated under no load! If the actual output power is very small, connected to the input or output end in series (Figure please connect a resistor with proper resistance at the output end in parallel to increase 2). the load, or use our company's products with a lower rated output power. Vin +Vout REG DC DC GND 0V REG Vin Recommended testing and application circuit If you want to further decrease the input/output GND ripple, an "LC" filtering network may be connected to +Vout DC DC 0V (Figure 2) the input and output ends of the DC/DC converter, see Overload Protection Under norm al operating conditions, the output (Figure 1). L L +Vo Vin DC DC Cin circuit of these products has no protection against overload. The simplest method is to connect a Cout G ND self-recovery fuse in series at the input end or add a 0V circuit breaker to the circuit. (Figure 1) It should also be noted that the inductance and the No parallel connection or plug and play. frequency of the "LC" filtering network should be staggered with the DC/DC frequency to avoid mutual Note: 1. All specifications measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified. 2. Only typical models listed, other models may be different, please contact our technical person for more details. 3. Operation under minimum load will not damage the converter; However, they may not meet all specification listed. interference. 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, provided the safe and reliable operation is ensured, the recommended capacitance of its filter capacitor sees (Table 1).
