20A 48V ZVS, 10x14 mm buck regulator modules, by Vicor

February 26, 2017 // By Graham Prophet
PI3525-00-LGIZ is the latest addition to Vicor's Cool-Power ZVS buck regulators with a 48V (30-60 Vin) input. The PI352x is a higher current offering than the existing PI354x portfolio enabling scalable power options for 48V Direct to Point of Load (PoL) applications.

The device is a 5V output regulator, supplying up to 20A, packaged in a 10 x 14mm LGA SiP package. 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 mm ² 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 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 datacentre applications.


Specifically, the added part in the range is rated to deliver 20A at 5V; this will shortly be augmented by modules in the same outline for 3.3V at 21A; and for 12V at 17A.
