APPLICATIONS The IB_(X)T-1W Series are specially designed for applications where a group of polar power supplies are 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 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. Note: 1. IB_XT-1W series designing; 2. IB_XT-1W series have no 3,6,8,9pin,for example IB0505XT-W75.

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 greatest capacitance of its filter capacitor 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.

The simplest method is to connect a self-recovery fuse in series at the input end or add a circuit breaker to the circuit. When the environment temperature is higher than 71C, the product output power should be less then 60% of the rated power.
