  AN-777 LM2577 Three Output, Isolated Flyback Regulator (Rev. B)
  PDF, 278 Kb, 修订版: B, 档案已发布: Apr 23, 2013
  Many voltage regulator applications require multiple outputs, such as a computer's power supply or aregulator used to meet the voltage requirements inside an automobile. Some of these applications requireisolation between the regulator's input and output for protection and separate ground specifications. Usingthese criteria, a LM2577 simple switcher flyback regulator has been designed with m

  AN-1149 Layout Guidelines for Switching Power Supplies (Rev. C)
  PDF, 82 Kb, 修订版: C, 档案已发布: Apr 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
