APPLICATIONS
The FB_N-1W Series are specially designed for applications where a group of polar power supplies are isolated from the input power supply in a distributed power supply system on a circuit board. These products apply to: 1) Where the voltage of the input power supply is fixed (voltage variation ≤ ±10%); 2) Where isolation is necessary between input and output (isolation voltage ≤5200VDC); 3) Where the regulation of the output voltage and the output ripple noise are not demanding. Such as: purely digital circuits, ordinary low frequency analog circuits, and IGBT power device driving circuits. These products don’t apply to: 1) Wh ere the input supply voltage is varied (variation≥±10%), otherwise our company ’s WRA series is recommended; 2) Circuits in which the output voltage regulation is demanding, otherwise our company’s IA Series or WRA Series are recommended; MODEL SELECTION FB0505N-1W Product Series Input Voltage Output Voltage Package Style Rated Power MORNSUN Science& Technology Ltd.

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. Recommended testing and application circuit If you wa nt 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). L Single Output Vin GND +Vo DCCin L DC Cout (Figure 1) It should also be noted that the inductance and the frequency of the “LC” filtering 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 too big, a startup problem might arise. For ev ery channel of output, provided the safe and reliable operation is ensured, the greatest capacitance of its filter capacitor sees (Table 1).

Output Voltage Regulation and Over- voltage Protection Circuit The simplest de vice 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). Single Output Vin GND +Vout DCDC REG REG (Figure 2) 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 add a circuit breaker to the circuit.
