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 - AN-2155 Layout Tips for EMI Reduction in DC/ DC Converters (Rev. A)PDF, 3.6 Мб, Версия: A, Файл опубликован: 23 апр 2013
This application note will explore how the layout of your DC/DC power supply can significantly affect theamount of EMI that it produces. It will discuss several variations of a layout analyze the results andprovide answers to some common EMI questions such whether or not to use a shielded inductor. - AN-1149 Layout Guidelines for Switching Power Supplies (Rev. C)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 - AN-2162 Simple Success With Conducted EMI From DC-DC Converters (Rev. C)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-1229 SIMPLE SWITCHER PCB Layout Guidelines (Rev.
