Expanded CoolPower ZVS Regulator Portfolio with 48 V Buck Regulators

Vicor Corporation announced the expansion of its Picor Cool-Power™ ZVS Point-of-Load Regulator portfolio with the introduction of high efficiency PI3542, PI3543, PI3545, and PI3546 buck regulators. The entire Cool-Power portfolio is characterized by products with benchmark efficiency and density performance that are simple to use, accelerating time to market.

Enables 48 V direct to PoL high performance step-down regulation Zero-Voltage Switching (ZVS) topology provides unparalleled efficiency over 96% High density 10 x 10 x 2.5 mm LGA System in Package (SiP) module for power delivery over 100 W.

Advanced features including constant current control for lighting and battery applications PI354x Cool-Power ZVS Buck Regulators utilise the integration of a high performance ZVS topology that enables 48 V direct to PoL without sacrificing performance. With step-down regulation from a higher voltage source, engineers can deploy more efficient power distribution architectures, reduce I2R losses, and eliminate costly and inefficient intermediate conversion stages. 

PI354x series operates from 36 Vin to 60 Vin Regulates an output voltage ranging from 2.2 V to 14 V, with output current delivery up to 10 A.

Power delivery can be further increased by using single wire current sharing without any additional components.

The PI354x Cool-Power ZVS Buck Regulators are designed for a wide range of applications leveraging higher voltage distribution, including: telecom, network infrastructure, datacenters, industrial, battery, and lighting applications. 

The PI354x series expands and enhances the Vicor Power Component Design Methodology. When used in conjunction with Vicor’s front-end products and Factorized Power products, the PI354x series can enable a complete power chain from AC or HVDC (200 V+) source to PoL.
