The PI3525-00-LGIZ is the latest addition to the Cool- Power ZVS Buck Regulator portfolio with a 48V (30 – 60VIN ) 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 PI3525-00-LGIZ is a 5V output regulator, supplying up to 20A, 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. The PI3525-00-LGIZ requires only an output inductor and minimal passives for a complete cost effective design that consumes less than 740 mm2 of PCB real estate.
