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 3000VDC); 3) Where the regulation of the output voltage and the output ripple and noise are not demanding. Such as: purely digital circuits, ordinary low frequency analog circuits and IGBT power device driven circuits, etc. F1212AS-1W F1215AS-1W F1505AS-1W F2405AS-1W F2409AS-1W F2412AS-1W F2415AS-1W ISOLATION SPECIFICATIONS Item Isolation voltage Isolation resistance Isolation capacitance Test condition Tested for 1 minute and 1mA max Test at 500VDC Min 3000 1000 60 Typ Max Units VDC M pF OUTPUT SPECIFICATIONS Item Output power Test condition Min 0.1 For Vin change of 1%(3.3V output) For Vin change of 1%(others) Typ Max 1 1.5 1.2 12 10 8.3 6.8 6.3 20 15 15 15 15 % Units W MODEL SELECTION Line regulation F0505AS-1W Rate Power Package Style Output Voltage Input Voltage Product Series 10% to 100% full load(3.3V output) 10% to 100% full load(5V output) Load regulation 10% to 100% full load(9V output) 10% to 100% full load(12V output) 10% to 100% full load(15V output) Output voltage accuracy Temperature drift 100% full load 20MHz bandwidth Full load, nominal input voltage See tolerance envelope graph 0.03 50 100 100 %/C mVp-p KHz MORNSUN Science& Technology co.,Ltd.

L L Vin Cin +Vo DC DC (Figure 1) Cout GND 0V 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 recommended 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. No parallel connection or plug and play. APPLICATION NOTE Requirement On Output Load To ensure this module can operate efficiently and reliably, a minimum load is specified for this kind of DC/DC converter in addition to a maximum load (nam ely full load). 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.
