Vicor – PI3526-00-LGIZ: Cool-Power ZVS Buck Regulator

The PI3526-00-LGIZ is the latest addition to the Cool-Power ZVS Buck Regulator Portfolio with a 48V (30 – 60 VIN) input. The PI352x is a higher current offering to the existing PI354x portfolio, enabling scalable power options for 48V Direct to Point-of-Load (PoL) applications. The PI3526-00-LGIZ is a 12V output regulator, supplying up to 18A, packaged in a 10 x 14mm LGA SiP package. Offering all the same industry leading features of Vicor’s existing 48V Cool-Power ZVS buck regulators, the PI352x portfolio extends performance by delivering twice the power of the PI354x regulators using only a 40% larger package.
