Vicor PI3523-00-LGIZ (PI3523) Cool-Power ZVS buck regulator

Vicor has extended the Cool-Power 48 V ZVS 20 A buck regulator portfolio with the release of the PI3523-00-LGIZ (PI3523).

The PI352x family offers 20 A solutions complementing the previously released 10 A, 48 V_IN PI354x family, enabling scalable power options for 48 V direct to point-of-load (PoL) applications. The PI3523 is a 48 V_IN, 3.3 V_OUT nominal buck regulator capable of supplying up to 22 A. The regulators enable 48 V_IN to 20 A point-of-load voltages spanning 2.2 to 14 V_OUT.

Offering all the features of the existing 48 V Cool-Power ZVS buck regulators, the PI352x portfolio extends performance by delivering twice the power of the PI354x regulators in a 40% larger package. The PI3523 requires only an output inductor and minimal passives for a design that consumes less than 740 mm² of PCB space. Designed to be easily paralleled in combinations of up to three regulators, the regulators can be scaled to support higher current loads.

The range addresses the growing need for 48 V direct-to-PoL solutions in applications including lighting, communications, automotive equipment, data centres and more. The regulators are focused on high power density and high efficiency while delivering ease of use.
