It should also be noted that the inductance and the frequency of the “LC” filtering network +Vo DC DC Cin Cout 0V (Figure 1) Dual O u tput Vi n 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 parallel to L GND APPLICATION NOTE 1) Requirement on output load To ensure this module can operate efficiently and reliably, During operation, the minimum 0V L Cout R EG REG +Vout REG -Vout REG +Vout 0V DC DC GND S ingle O utput Vi n R EG DC DC GND 0V (Figure2) 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 greatest capacitance of its filter capacitor sees (Table 1). 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 (Figure2). 4) Overload Protection Under normal operating conditions, the output circuit of these products has no protection against overload.
