  • AN-1149 Layout Guidelines for Switching Power Supplies (Rev. C)
    PDF, 82 Kb, Revision: C, File published: 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
