These products apply to: 1) Where the voltage of the input power supply is fixed (voltage variation 5%); 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 demanding.

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 (IF_S(D) -W25 Series). Filtering *Supply voltage must be discontinued at the end of short circuit duration. TYPICAL CHARECTERISTICS Temperature Derating Graph In some circuits which are sensitive to noise and ripple, a filtering capacitor may be added to the DC/DC output end and input end to reduce the noise and ripple. However, the capacitance of the output filter capacitor must proper. If the capacitance is too big, a startup problem might arise. For every channel of output, providing the safe and reliable operation is ensured, the greatest capacitance of its filter capacitor refer to (Table 1).

To get an extrem ely low ripple, an "LC" filtering network may be connected to the input and output ends of the DC/DC converter, which may (0. 161) IFXXXXD-1W DIP Package (0.787) produce a more significant filtering effect. 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 (Figure 1). 0.50 (0.020) (0.03 5) (0.60) (0 .30 ) (0.3 94) (0.161 ) (Side View) 6.00 (0. 236 ) L L 12 4 (Bottom View) Vin 1 14 9 7 C +Vo DC DC (Figure 1) C GND (0.079) (0.5 00) 0V RECOMMENDED FOOT PRINT Top view,grid:2.54*2.54mm(0.1*0.1inch) , diameter:1.00mm(0.039inch) 14 1 2 4 1 9 7 Overload Protection Under normal operating conditions, the output circuit of these products has no protection against over-current and short-circuits. The simplest method is to connect a self-recovery fuse in series at the input end or add a circuit breaker to the circuit.
