These integrate control circuitry, power semiconductors and support components within the SiP.
Vicor Corporation 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 (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 per cent 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.
