- 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 - AN-1229 SIMPLE SWITCHER PCB Layout Guidelines (Rev. C)PDF, 374 Kb, Revision: C, File published: Apr 23, 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 Mb, Revision: B, File published: Apr 23, 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
