DC-DC Non-Isolated Regulated

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. For buck regulators there is an optional I2C  interface to enable user programmability.  In addition to both boosting and bucking a wide range input voltage – providing a regulated, adjustable output voltage – a factorized power architecture (FPA) can be implemented with Vicor’s PRM® used with Vicor’s VTM®, for a complete isolated DC-DC solution with high efficiency and power density.
