  PDF, 82 Кб, Версия: C, Файл опубликован: 23 апр 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

  PDF, 2.5 Мб, Версия: C, Файл опубликован: 24 апр 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-1520 A Guide to Board Layout for Best Thermal Resistance for Exposed Packages (Rev. B)
  PDF, 9.2 Мб, Версия: B, Файл опубликован: 23 апр 2013
  This thermal application report provides guidelines for the optimal board layout to achieve the best thermalresistance for exposed packages. The thermal resistance between junction-to-ambient (ОёJA) is highlydependent on the PCB (Printed Circuit Board) design factors. This becomes more critical for packageshaving very low thermal resistance between junction-to-case such as exposed pad TSSOP
