ZVS PI33/PI34/PI35 Buck Family of Switching Regulators
Vicor’s maximum power density and flexibility parts for high-efficiency point-of-load DC-DC regulation
Vicor's PI33, PI34, and PI35xx series ZVS buck switching regulators offer board-level designers maximum power density and flexibility for high-efficiency point-of-load DC-DC regulation. The integration of a high-performance zero-voltage switching (ZVS) topology increases point-of-load performance, providing exceptional power efficiency up to 98%. The ZVS regulators are highly integrated with control circuitry, power semiconductors, and support components in a high-density system in package (SiP). The device can also be configured to operate in constant current mode.
