Increasing Point of Load Performance
Providing Best in Class Power Efficiency Cool-Power® ZVS Regulator Portfolio

DC-DC Non-Isolated Regulated

Vicor's range of buck and buck-boost DC-DC converters use a Zero Voltage Switching (ZVS) topology, enabling high frequency operation while minimizing switching losses and maximizing efficiency. The high switching frequency operation reduces the size of the external filtering components, improves power density, and enables fast dynamic response to line and load transients.
