The new Cool-Power ZVS buck, PI3325-00-LGIZ, represents the highest current output ZVS buck to date for 24/28-V applications, providing a regulated 5-V output at up to 20 A. Packaged within a 10x14x2.5-mm LGA SiP package, the PI3325-00-LGIZ addresses the continued need for high power density across a growing spectrum of applications. It also offers pin-for-pin compatibility to a 48-V input version ZVS buck, the PI3525-00-LGIZ, enabling designs to be quickly ported from 24-VIN capability to 48 VIN.
The PI3325-00-LGIZ requires only an output inductor and minimal passives for a complete, cost-effective, compact design that takes up less than 740 mm2 of PCB real estate. Higher current is also achievable by parallel operation of the regulator. The PI3325-00-LGIZ represents one regulator within a new portfolio of higher current 24-V 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. Key attributes of the Cool-Power ZVS regulators’ high performance include zero-voltage switching topology, high silicon integration, and high-density LGA SiP packaging. These high-performance regulators are also simple to use ensuring designs that achieve first-pass design success.
