How to design modular DC-DC systems, Part 2: Filter design
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
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 […]
How to design modular DC-DC systems
When designing a modular DC-DC system, it is important to look at the entire power-delivery system from source to load to achieve the desired functionality and performance. This tutorial series examines the modular DC-DC system design process and walks through an example set of system loads and the process to supply those from a given […]
ZVS buck regulators handle 22 A in BGA tin-lead packages
Vicor has released two new ZVS buck regulators the PI3323 and the PI3325, with an extended operating temperature range of –55 to +120°C and an optional tin-lead 10 x 14mm SiP BGA package for Mil COTS applications. These high-density and high-efficiency buck regulators have a 14 – 42V input voltage range and support nominal outputs […]
Modules down-convert 48 V to handle 12-V loads
Vicor’s new DCM3717 enables customers in data center, automotive and industrial markets to quickly deploy high-performance 48V power delivery for legacy 12V loads while achieving significant power-system size, weight and efficiency benefits. The DCM3717 operates from a 40 – 60V SELV input, is non-isolated, and provides a regulated output with a range of 10.0 – […]
Power chipset provides 650 A continuous, 1,200-A peak for high-performance GPU, CPU, ASIC processors
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 […]
