May 26, 2015 - Vicor ( www.vicorpower.com ; CEO Ki-Cheon Jeong) has expanded its Picor Cool-Power™ ZVS Point-of-Load regulator portfolio with the launch of the high-efficiency PI3542, PI3543, PI3545, and PI3546 Buck regulators. The entire Cool-Power portfolio features ease-of-use, high-density, and high-efficiency, enabling customers to achieve faster time-to-market.

Provides high-performance step-down regulation from 48V to PoL
Applying ZVS topology provides the highest efficiency of over 96%
High-density 10 x 10 x 2.5 mm LGA SiP (System in Package) module delivering over 100W of power
Enhanced performance, including constant current control for lighting and battery applications


The PI354x Cool-Power ZVS Buck regulators feature a high-performance Zero-Voltage Switching (ZVS) topology that enables power conversion from 48V to PoL without performance degradation. Designers can utilize step-down regulation from a high-voltage source to achieve more efficient power distribution, minimize I2R losses, and eliminate costly, inefficient intermediate conversion stages.

The PI354X series operates from 36Vin to 60Vin.
Provides output current up to 10A and output voltage regulation from 2.2V to 14V
Power capacity can be increased by utilizing a single-wire current sharing method without external additional components.

The PI354x Cool-Power ZVS Buck regulators are designed for applications in telecom, network infrastructure, data centers, industrial, battery, and lighting where high-voltage distribution architectures are available.

The PI354x series expands and strengthens Vicor's power component design solutions. When used with Vicor's front-end and factored power products, the PI354x enables the design of a complete power chain, from an AC or HVDC (200 V or higher) source to the point of load (POL).

Purchase information
Picor Cool-Power PI354X ZVS Buck regulators are available for order through Vicor and authorized Vicor distributors. Pricing for the PI354x family starts at $12.80 in 1,000-unit quantities.
