New buck-boost regulators provide over 200W and over 98% peak efficiency

Vicor has announced the expansion of its Picor Cool-Power ZVS Point of Load (POL) regulator portfolio with the introduction of the new, high-efficiency PI3749, PI3751, and PI3755 series buck-boost regulators. By minimizing switching losses, Picor ZVS topology enables efficiencies over 98% maintaining a high efficiency over the specified Vin range. High-frequency operation (up to 2.5MHz) enables best in class power density and transient response. Easy-to-use LGA System in Package (SiP), with integrated controller, power switches and support components, reduce design risks and speed time to market. The Picor Cool-Power PI3749 buck-boost regulator covers a wide range of high-performance applications including computing, communications, industrial, LED lighting and battery systems. The PI3749 operates from 16Vin to 34Vin, regulates an output voltage from 12V to 34V and provides output current up to 11.5A for power delivery over 200W. Power delivery can be further increased by using single wire current sharing without any additional components. The Picor Cool-Power PI3751 and PI3755 buck-boost regulators are designed for Factorized Power Architecture (FPA) and work in conjunction with VI Chip VTM current multipliers to address high-performance point-of-load power delivery to processors (including VR12.5+ compliance) and memory (including DDR3/4 compliance) in server and data centre applications.
