12V, 24V or 48V direct to point-of-load regulators that offer 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%. These buck regulators are highly integrated with control circuitry, power semiconductors and support components, in a high density package.
