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 1000VDC); 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. 12 10.8-13.2 24 21.6-26.4 MODEL SELECTION D050505S-1W Rated P ower Package Styl e The 2nd Output Voltage The 1st Output Voltage Input Voltage Product Series COMMON SPECIFICATIONS Item Storage humidity Operating temperature Storage temperature Lead temperature Temp. rise at full load Short circuit protection* 1.5mm from case for 10 seconds 15 -40 -55 Test conditions Min Typ Max 95 85 125 300 25 1 Free air convection Plastic (UL94-V0) 3500 2.3 K hours g s C Units % MORNSUN Science & Technology co.,Ltd.

During operation, make sure the specified range of input voltage is not exceeded, 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 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 testing and application 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).

See below recommended circuits for more details. +Vo1 Cout Vin Cin DC DC L Cout 0V1 +Vo2 0V2 GND TYPICAL CHARACTERISTICS (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 every channel of output, provided the safe and reliable operation is ensured, the greatest capacitance of its filter capacitor sees (Table 1).

The simplest method is to connect a self-recovery fuse in series at the input end or add a circuit breaker to the circuit.
