From the Editors Desk (Feb Newsletter)

There is so much happening in power conversion/power management these days. So many applications are spurring development of new power components, circuits, topologies, control methods, test instruments, analysis techniques and more. This issue for example features an article on a new approach to designing smart electronic loads for burn-in testing of server power supplies. It continues the discussion of how to estimate output current tolerance for PSR flyback converters. There’s also another dose of “EMI for Wisdom Seekers” plus an extensive article on how to layout a board with a power supply and an MCU…  Read more»

The Case Of The MOSFET Failure

by Paul L. Schimel, PE

I recently had a fun problem come across my desk. It’s a common sequence of events. My customer built a power converter, they used my MOSFETs in the converter. The converter failed, the failure took out the MOSFET. Having been through a few of these sorts of things, I know the difficulty firsthand, as a customer as a vendor and as a senior FAE existing between the two. To get to the root cause, there is a lot of information that needs to be shared on many levels.
