Vicor introduces the first in a new family of 20 Amp 48V Cool-Power ZVS Buck Regulators

February 23, 2017


ZVS Buck RegulatorsSummary: 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 10x14 mm 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. Designed to be easily paralleled in combinations of up to three regulators, the PI352x regulators can be scaled to support applications with even higher load currents.


The PI352x family addresses the growing need for 48V Direct to PoL solutions in many applications including lighting, communications, automotive equipment, and datacenter applications. The Cool-Power ZVS Regulators are focused on high power density & high efficiency while being simple to use. The end result is first pass design success with best in class performance.
