<description>&lt;b&gt; WE-FB Flyback Transformer suitable for LT3573/ LT3574/ LT3575/ LT3748
&lt;br&gt;
&lt;br&gt;
&lt;br&gt;&lt;b&gt; Characteristics
&lt;br&gt;
&lt;br&gt;&lt;/b&gt;&lt;/b&gt; easy design in solution 
&lt;br&gt;
&lt;br&gt; less external components needed 
&lt;br&gt;
&lt;br&gt; small board space 
&lt;br&gt; 
&lt;br&gt; low cost 
&lt;br&gt;
&lt;br&gt; no optocoupler needed! 
&lt;br&gt;
&lt;br&gt; long term reliability voltage control 
&lt;br&gt;
&lt;br&gt; no aging 
&lt;br&gt;
&lt;br&gt; same external parts for different output voltages 
&lt;br&gt;
&lt;br&gt; easy design of custom power supply due to standard circuit and change of transformers and two components for feedback loop 
&lt;br&gt;
&lt;br&gt; Isolation voltage up to 2.5 kV 
&lt;br&gt;
&lt;br&gt;
&lt;br&gt;&lt;b&gt; Applications 
&lt;br&gt;
&lt;br&gt;&lt;/b&gt; Isolated power design 
&lt;br&gt;
&lt;br&gt; Sensor interfaces 
&lt;br&gt;
&lt;br&gt; Isolated telecom converters 
&lt;br&gt;
&lt;br&gt; Power over Ethernet 
&lt;br&gt;
&lt;br&gt;
&lt;br&gt;The &lt;b&gt; "VALUE"shown for symbol and packaging is Ooutput Voltage 1 Output Current 1&lt;/B&gt;&lt;BR&gt;
