ZVS buck regulators

12 June 2013 Power Electronics / Power Management

Vicor has expanded its Picor Cool-Power ZVS buck regulator product line for high-efficiency point-of-load DC-DC regulation.

Optimised for 12 V operation, the new PI34XX series of buck regulators is aimed at a host of embedded applications in computing, telecommunications, industrial and other environments, delivering over 95% peak efficiency for 12 V to 3,3 V regulation and up to 15 A.

The integration of a high-performance ZVS (zero-voltage switching) topology within a high-density (10 x 14 x 2,6 mm) System-in-Package (SiP) enhances point-of-load DC-DC regulation by reducing the switching losses associated with conventional hard-switching buck regulators. The reduction of switching losses enables a higher-efficiency and higher-density regulator that is also simple to use.

PI34XX series buck regulators integrate control circuitry, power semiconductors and support components within the SiP. They require only an external inductor with minimal capacitors to form a complete DC-DC switching mode buck regulator.
