Proper Layout and Component Selection Controls EMI

Focus:

The causes of noise and EMI in switching regulator circuits is explained in terms of the operation of different types of regulator topologies including buck, boost, flyback, and SEPIC. Techniques for reducing noise and EMI are discussed along with their possible impact on other aspects of regulator performance. Causes and fixes for common-mode noise, unwanted electric and magnetic fields, and crosstalk are discussed. Other topics covered include the impact of inductor design, transformer design, pc board layout, and bypass capacitors on EMI.

What you’ll learn:

• How to layout a printed circuit board (PCB) for a switching regulator design to minimize EMI
• How to select or design inductors, transformers, and capacitors to minimize EMI in switching regulator designs
• How to understand the causes of EMI in switching regulator designs
