<div class="content"><p><b>Abstract</b><br />The power switch has considerably reduced common-mode interference and relatively reduced circuit complexity. The power switch is formed of a semiconductor chip on a leadframe. A first terminal of the semiconductor chip is connected to the active potential and a second terminal for inactive potential is connected to the leadframe. The second terminal is either the drain of a transistor or the anode of a diode.</p><p><a href="http://www.google.com/patents/pdf/EMC_optimized_power_switch.pdf?id=qCYLAAAAEBAJ&output=pdf&sig=G3cDED7c0eiRJVQ5jIm9PzgkZpI"><font color="#336699">EMC-optimized power switch(美国EMC技术专利)</font></a></p></div>
