Vicor has announced the expansion of its Picor Cool-Power ZVS Point of Load (POL) Regulator portfolio with the introduction of its high efficiency PI3749, PI3751, and PI3755 buck-boost regulators. By minimising switching losses, Picor’s 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. The easy-to-use LGA SiP, with integrated controller, power switches and support components, reduces design risk and speeds 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.

Packaged in a 10x14x2.5mm LGA SiP module, PI3749 operates from 16 to 34VIN, regulates an output voltage from 12 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 Factorised Power Architecture (FPA) and work in conjunction with VI Chip VTM current multipliers to address high performance POL power delivery to processors (including VR12.5+ compliance) and memory (including DDR3/4 compliance) in server and data centre applications. The regulators enable 48V direct to POL when combined with VTM, and are packaged in 10x14x2.5mm (PI3751) and 10x10x2.5mm (PI3755) LGA SiP modules.

The PI37XX series expands the portfolio of high performance, high density Picor Cool-Power ZVS POL Regulators. The entire Cool-Power portfolio is characterised by products that offer benchmark efficiency and density, and are simple to use, accelerating time to market.

The Picor Cool-Power PI3749 and PI375X buck-boost regulators can be ordered today from Vicor and Vicor authorised distributors. PI37XX pricing starts at $14.50, $18.50 and $14.80 in 1,000 quantities, respectively, for the PI3749, PI3751, and PI3755.
