Operating Temp.(oC) APPLICATION NOTE RECOMMENDED CIRCUIT Requirement on output load To ensure this module can operate efficiently and reliably, During operation, 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 L +Vo1 L C Vin DC DC C 0V1 +Vo2 L GND C 0V2 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. Recommended circuit If you want to further decrease the input/output ripple, an “LC” filtering network may be (Figure 1) +Vo1 Vin REG 0V1 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 DC DC +Vo2 GND 0V2 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 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). +Vo1 REG Vin 0V1 DC DC +Vo2 REG GND 0V2 (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 operating conditions, the output circuit of these products has no protection EXTERNAL CAPACITOR TABLE (TABLE 1) Vin(VDC) Cin(uF) Cout(uF) Vout(VDC) 3.3/5 4.7 3.3/5 4.7 It’s not recommended to connect any external capacitor in the application field with less than 0.5 watt output. 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.
