Vicor's PI3741-0x series is a high efficiency, wide range DC-DC ZVS buck-boost regulator with two output range configurations that utilize the same high density system-in-package (SiP). Integrating controller, power switches, support components, and a high performance zero voltage switching (ZVS) topology within the PI3741-0x increases point-of-load performance while providing best-in-class power efficiency.

The ZVS architecture also enables 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.
