Vicor Corporation Picor PI354x Cool-Power ZVS buck regulators

Vicor Corporation has expanded its Picor Cool-Power ZVS Point-of-Load Regulator portfolio with the introduction of high-efficiency PI3542, PI3543, PI3545 and PI3546 buck regulators. The buck regulators are designed for a range of applications leveraging higher voltage distribution, including telecom, network infrastructure, data centres, industrial, battery and lighting applications.

PI354x Cool-Power ZVS buck regulators utilise the integration of high-performance zero-voltage switching (ZVS) topology that enables 48 V direct to PoL without sacrificing performance, providing efficiency over 96%. With step-down regulation from a higher voltage source, engineers can deploy efficient power distribution architectures, reduce I2R losses and eliminate intermediate conversion stages.

The series operates from 36 to 60 Vin and regulates an output voltage ranging from 2.2 to 14 V, with output current delivery up to 10 A. Power delivery can be further increased by using single-wire current sharing. Other features include: a high-density 10 x 10 x 2.5 mm LGA SiP module for power delivery over 100 W; and constant current control for lighting and battery applications.
