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 and noise are not demanding. Such as: purely digital circuits, ordinary low frequency analog circuits and IGBT power device driven circuits, etc. Isolation capacitance Isolation resistance Isolation voltage Designing. Note: The D_T-1W series also are available in our company.

APPLICATION NOTE Min Typ Max 95 -40 -55 15 85 125 25 260 1 Free air convection Plastic (UL94-V0) 3500 2.1 K hours g S C Units % 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 (namely 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 (D_T -1W). Recommended testing 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 (Figure1). L L Test Conditions 1.5mm from case for 10 seconds TYPICAL CHARECTERISTICS +Vo1 C Vin C DC DC (Figure 1) L C 0V1 +Vo2 0V2 GND It should also be noted that the inductance and the frequency of the "LC" filtering network should be Ambient Temperature ( C ) 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).
