Vicor’s new PI3526-00-LGIZ is the latest addition to its Cool-Power ZVS Buck Regulator portfolio supporting a 48V (30-60Vin) input. The PI352x is a higher current offering compared to Vicor’s 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 10x14mm LGA SiP package.

Offering all the same features of Vicor’s existing 48V Cool-Power ZVS Buck Regulators, the PI352x portfolio delivers twice the power of the PI354x regulators using only a 40% larger package. The PI3526-00-LGIZ requires only an output inductor and minimal passives for a complete design that consumes less than 740mm2 of PCB real estate. Designed to be paralleled in combinations of up to three regulators, the PI352x regulators can be scaled to support applications with 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 and high efficiency while being simple to use.
