  AN-2162 Simple Success With Conducted EMI From DC-DC Converters (Rev. C)
  PDF, 2.5 Mb, Revisión: C, Archivo publicado: abr 24, 2013
  Electromagnetic Interference (EMI) is an unwanted effect between two electrical systems as a result ofeither electromagnetic radiation or electromagnetic conduction. EMI is the major adverse effect caused bythe application of switch-mode power supplies (SMPS). In switching power supplies EMI noise isunavoidable due to the switching actions of the semiconductor devices and resulting disconti

  AN-1149 Layout Guidelines for Switching Power Supplies (Rev. C)
  PDF, 82 Kb, Revisión: C, Archivo publicado: abr 23, 2013
  When designing a high frequency switching regulated power supply layout is very important. 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
