Vicor releases its highest current output ZVS buck to date

The Cool-Power ZVS, PI3325-00-LGIZ, is the highest current output ZVS buck to date for 24V/28V applications, says Vicor. It provides a regulated 5.0V output at up to 20A.

Packaged within a 10 x 14 x 2.5mm LGA SiP, the PI3325-00-LGIZ addresses the continued need for high power density across a growing spectrum of applications, explains Vicor. It also offers pin-for-pin compatibility to a 48V input version ZVS Buck, the PI3525-00-LGIZ, enabling designs to be quickly ported from 24VIN capability to 48VIN.

The PI3325-00-LGIZ requires only an output inductor and minimal passives for a complete, cost-effective, compact design, says Vicor. It occupies less than 740mm2 of PCB real estate. 

Higher current is also achievable by parallel operation of the regulator. The PI3325-00-LGIZ represents one regulator within a portfolio of higher current 24V ZVS bucks already, or soon to be, released.

Vicor’s Cool-Power ZVS regulators deliver more power at higher temperatures than competitive devices, without sacrificing power density or efficiency, claims Vicor. Key attributes to the Cool-Power ZVS regulators’ high performance include zero-voltage switching topology, high silicon integration, and high density LGA SiP. 

Headquartered in Andover, Massachusetts, USA, Vicor designs, manufactures and markets modular power components, to enable customers to efficiently convert and manage power from the power source to the point of load. 

Vicor’s Power Component Design Methodology enables power system designers to reap all of the benefits of modular power component design – predictable component and system functionality and reliability, fast design cycles, and easy system configurability, re-configurability and scaling – while achieving system operating efficiency, power density and economy, says the company. Using Power System Designer, engineers can select from a portfolio of proven Vicor power components to architect, optimise and simulate the complete power system, all the way from their input sources to the points of load. Vicor believes that this approach to power system design delivers fast time-to-market and state-of-the-art performance while minimising the possibility of last minute surprises and delays that can occur with conventional or custom design methodologies.
