In this article the design of a polarity inverting converter will be discussed. PDF , 3. It will discuss several variations of a layout analyze the results andprovide answers to some common EMI questions such whether or not to use a shielded inductor. PDF , 1. The method is explained in an easy to followstep-by-step manner so that a power supply designer can start performing these measurements in a shortamount of time.

Using agood layout can solve many problems associated with these types of supplies. The problems due to a badlayout are often seen at high current levels and are usually more obvious at large input to output voltagedifferentials. Some of the main problems are loss of regulation at high output current. In switching power supplies EMI noise isunavoidable due to the switching actions of the semiconductor devices and resulting disconti.

PDF , 9. This becomes more critical for packageshaving very low thermal resistance between junction-to-case such as exposed pad TSSOP. Texas Instruments.
