APPLICATIONS
The IB_LD-1W & IB_LS-1W Series are specially designed for applications where a single power supply is highly isolated from the input power supply in a distributed power supply system on a circuit board. 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 1000VDC); 3) Where the regulation of the output voltage and the output ripple and noise are demanded.

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 (IB_LD -W25/IB_LS-W25 series). Recommended circuit If you want to further

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).

*Test ripple and noise by "parallel cable" method. See detailed operation instructions at Testing of Power Converter section, application notes.
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.

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
