ZVS Buck Regulator Meets Point-Of-Load Needs


Vicor Corporation
has expanded its Picor Cool-Power® ZVS Buck Regulator product line for 
high efficiency point-of-load DC-DC regulation. Optimized for 12 V operation (8 V to 18 Vin), these new PI34XX series buck regulators increase performance for 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 topology within a high density (10 mm x 14 mm 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 and require only an external inductor with minimal capacitors to form a complete DC-DC switching mode buck regulator.

The Picor Cool-Power portfolio currently consists of the PI31XX seriesof isolated converters and the PI33XX and PI34XX series of ZVS Buck Regulators. Future products in the family will include additional ZVS Buck Regulators with different voltage/current capability, ZVS Buck-Boost Regulators, and ZVS Boost Regulators, all of which are expected to set new industry performance benchmarks.

Picor PI34XX-00-LGIZ Cool-Power ZVS Buck Regulators are all priced at $9.84 for 1000-unit quantities.
