Characterizing and Selecting the VRM

VRMs and VRM controllers are often selected based on size, efficiency, price, or a relationship with the manufacturer. This often leads to a poor VRM selection, requiring additional engineering resources, greater time to market, as well as, higher BOM costs to correct the deficiencies. In this article, we evaluate the choices, define some useful figures of merit, and provide specific selection suggestions.

Target Impedance Limitations and Rogue Wave Assessments on PDN Performance

A common design technique for power distribution networks (PDN) is the determination of the peak distribution bus impedance that will assure that the voltage excursions on the power rail will be maintained within allowable limits, generally referred to as the target impedance. In theory, the allowable target impedance is determined by dividing the tolerable voltage excursion by the maximum change in load current.

Analog Devices' IEEE 802.3bt PD Controller Offers 99% Efficiency

Analog Devices, Inc., which recently acquired Linear Technology Corp., announces the LT4294 IEEE 802.3bt Powered Device (PD) interface controller for applications requiring up to 71W of delivered power. This new Power over Ethernet (PoE) standard – IEEE 802.3bt – increases the power budget to enable new applications and features, while supporting 10 Gigabit Ethernet (10GBASE-T) and maintaining backward compatibility with older IEEE 802.3af and 802.3at PoE equipment.
