Speaker: Rick Hartley, RHartley Enterprises


Title:Switch Mode Power Supply Layout 


Abstract: All Switch Mode Power Supplies have 4 to 5 circuit loops, all of which are important, but a couple are downright critical, in terms of PCB layout.  An improper PCB layout of a Switch Mode Supply will sometimes not function and will often have EMI issues.

In contrast, understanding what makes up a switcher circuit and knowing how to take care of the loops, during PC Board layout, will allow these supplies to operate flawlessly, with very high efficiency and will avoid EMI problems.

This short course will outline the different types of Switcher circuits (Buck, Boost, etc.), basic theory of operation, the impact of the various components, definition and behavior of the 5 loops, layout to isolate loops, layout to minimize noise & EMI and proper grounding technique.


Bio: Rick Hartley is the principal of RHartley Enterprises, through which he consults and teaches internationally.  Rick’s focus is on correct design of circuits and PC boards to prevent and/or resolve EMI, noise and signal integrity problems.  He has consulted with major corporations in the US and 12 other countries.  His career focused on computers, telecommunications and aircraft avionics, as well as the automotive and appliance space.  Rick has taught seminars at numerous conferences, including the IEEE EMC Symposium, PCB West, IPC Carolina, IPC Apex/Expo and others.  He is a member of the IPC DC Board of Directors, a past member of the Editorial Review Board of Printed Circuit Design Magazine and has written numerous technical papers and articles on methods to control noise, EMI and signal integrity.
