Vicor Corporation pi354x-00 and latest BGA package

The Description Of PI354x-00

The PI354x-00 is a family of high input voltage, wide input range DC-DC ZVS-Buck regulators integrating controller, power switches, and support components all within a high density System-in-Package (SiP). The PI354x-00 products are designed to operate within an SELV compliant system with steady state operation limited to 60V. The PI354x-00 products allow for transient voltage conditions up to 70V before shutdown is triggered. The integration of a high-performance Zero-Voltage Switching (ZVS) topology, within the PI354x-00 series, increases point of load performance providing best in class power efficiency. The PI354x-00 requires only an external inductor,two voltage selection resistors and minimal capacitors to form a complete DC-DC switching mode buck regulator.

PI354x-00 datasheet


Vicor has announced that Vicor will offer BGA package option for 48V Cool-Power ZVS Buck Regulator portfoli.The PI354x-00-BGIZ is the latest addition to the 48V Cool-Power ZVS Buck Regulator portfolio, offering a new BGA package option to the existing PI354x-00-LGIZ LGA series.

The PI354x Cool-Power ZVS Buck Regulator’s high performance ZVS topology enables 48V 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.Operating from 36VIN to 60VIN, the PI354x regulates an output voltage ranging from 2.2V to 14V and delivers an output current delivery up to 10A. Power delivery can be further increased by using single wire current sharing without any additional components.

The PI354x series is designed for a wide range of applications leveraging higher voltage distribution, including: telecom, network infrastructure, data centers, industrial, battery, and lighting applications.When used in conjunction with the Vicor front-end products and factorised power products, the PI354x series enables a complete power chain from AC or HVDC (200V+) source to PoL. The PI354x series expands and enhances the Vicor Power Component Design Methodology.
