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.

Note: 1.All specifications measured at TA=25C, humidity<75%, nominal input voltage and rated output load unless otherwise specified. 2. See below recommended circuits for more details. Test Conditions Min Typ Max 95 Units % 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. 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).

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 Operating Temp.( C) o safe and reliable operation is ensured, the recommended capacitance of its filter capacitor OUTLINE DIMENSIONS & PIN CONNECTIONS First Angle Projection RECOMMENDED FOOTPRINT Top view,grid:2.54*2.54mm(0.1 *0.1inch), diameter:1.00mm(0 .039inch) Single 7.50 12 0.50 (0.020) 4 6 sees (Table 1).

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 (A_M -W2/B_LM-W2 series).
