APPLICATIONS The E_T-W2&F_T-W2 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 3000VDC); 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.

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. Recommended 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). L L Test Conditions 1.5mm from case for 10 seconds Tested for 1 minute and 1mA max Test at 500VDC Epoxy Resin(UL94-V0) TYPICAL CHARACTERISTICS 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 Operating Temp.(oC) the output filter capacitor must be proper. If the capacitance is too big, a startup problem might arise.

Output Voltage Regulation and Over-voltage Protection Circuit The simplest device for output voltage regulation, over-voltage and over-current 2 2 0o C protection is a linear voltage regulator with overheat protection that is connected to the input or output end in series (Figure2).
