PDN Basics For Power Designers: Keep Impedance Flat. (Part two of the video series.)


PDN Basics For Power Designers: Keep Impedance Flat. (Part two of the video series.)

In modern electronic systems, the performance of FPGAs, CPUs, and other high-speed logic devices depends on the power distribution networks or PDNs that power these devices. Within these PDNs, power converters in the form of point-of-load regulators (POLs), voltage regulator modules (VRMs), dc-dc converters, and linear regulators play a crucial role. Yet, many engineers who develop these power converters may be unfamiliar with PDN concepts and how power converters affect PDN and system performance. In this three-part video series, Steve Sandler introduces three basic PDN concepts that developers of board-level power solutions need to understand.


Part 2: Keep Impedance Flat. In this 6-min. segment, Steve discusses power converter output impedance and why designers of board-level power converters need to keep their output impedance curves flat.
