Vicor Corporation is expanding its Picor Cool-Power ZVS Buck Regulator product line for high efficiency point-of-load DC-DC regulation. Optimised for 12 V operation (8 V to 18 Vin), these new PI34XX series buck regulators look to 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 Picor Cool-Power Zero-Voltage Switching (ZVS) Buck Regulator portfolio integrates a high performance ZVS topology within a high density (10 mm x 14 mm x 2.6 mm) System-in-Package (SiP) that 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.
“We recognise that some customers are constrained by a 12 V architecture and are not able to take advantage of higher line conversion with our existing regulators,” said Robert Gendron, Vice President, Picor Semiconductor Power Solutions, Vicor. “We optimised our 8 V to 36 V wide range regulators for a 12 V family, reducing the Vin range to 8 V to 18 V and further enhancing efficiency for 12 V usage.”
