Description

PI33/PI34/PI35xx Cool-Power 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 best-in-class power efficiency up to 98%. Cool-Power ZVS Regulators are highly integrated with control circuitry, power semiconductors and support components in a high density LGA System in Package (SiP).
