Today we announced the PI3525, the latest addition to our 48 V input Cool-Power ZVS Buck Regulator Portfolio that delivers 5 V at up to 20 A, double the current of previous components in the family. The new device has a wide 48 V (30-60 V) input and enables scalable power options for 48 V Direct to Point of Load (PoL) applications. The PI352x family will also include 3.3 V output (PI3523) and 12 V output (PI3526) regulators.

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 is packaged in a 10 mm x 14 mm LGA SiP package, requiring 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 48 V Direct to PoL solutions in many applications including lighting, communications, automotive equipment, and datacenter applications. The Cool-Power ZVS Regulators enable engineers to deliver high power density and high efficiency, while being simple to use.
