Presentation (pdf 402KB)

Overview: This presentation is designed to help a switching power supply engineer design a PCB that gives the best performance of their power supply while minimizing conducted and radiated electromagnetic interference (EMI). The presentation begins by identifying the types of EMI and classifying them according to how prevalent they are and how to deal with them. The second, main part of the presentation is a collection of tips and techniques that are presented during a walk-through of the design of a buck switching regulator PCB.

Length: 36 minutes

Published Date: July 2008

Topics covered in this online seminar include:

  • Self inductance influences impedance
  • Noise Coupling Mechanisms
  • Locating the high di/dt loops
  • "Ground rules"
  • Copper Requirements For High Current Paths
  • Component Placement Strategy
  • Gate Drive Layout Requirements
  • Power FETs and Decoupling
  • Switch Node design
  • Output Capacitors
  • Control Circuit Consideration
  • Noise considerations
  • Thermal Considerations

Presenter: Chris Richardson is an Applications Engineer in the Power Management Products group, Medium and High Voltage Division. His responsibilities are divided between lab work, bench evaluation of new ICs, written work such as datasheets and applications notes, and training for field engineers and seminars. Since joining National Semiconductor in 2001, Chris has worked mainly on synchronous buck controllers and regulators. In the last three years he has focused on products for the emerging high brightness LED market in the automotive and industrial areas. Chris holds a BSEE from the Virginia Polytechnic Institute and State University.
