How to design modular dc-dc systems, Part 2: Filter design

October 6, 2020 By Aimee Kalnoskas

safety protection systems

The previous tutorial in this series highlighted the performance, flexibility, and speed benefits of using power modules to design power systems then provided an overview of the modular design process. A modular design strategy is powerful, but it requires support circuitry in the power delivery network (PDN) to form a complete power system. This second […]

Autonomous wireless charging keeps robots running

September 30, 2020 By Lee Teschler

wireless charging

Buck-boost regulators efficiently power wireless charging stations for mobile robots. Logistics, delivery and inspection industries increasingly rely on mobile robotic fleets. These fleets have become large enough that their users are trying to find ways of recharging them that don’t rely on human operators. One means of automating the robotic charging process is through use […]

Power chipset provides 650 A continuous, 1,200-A peak for high-performance GPU, CPU, ASIC processors

May 18, 2020 By Aimee Kalnoskas

MCD4609 power chipset

Vicor Corporation announced a ChiP-set for high-performance GPU, CPU, and ASIC (XPU) processors powered directly from 48V. A driver, MCD4609, and a pair of MCM4609 current multiplier modules supply up to 650A continuous and 1,200A peak. Owing to their small footprint and low profile (45.7 x 8.6 x 3.2mm), current multipliers are placed close to […]
