98+% Efficient 200W Buck-Boost Regulators

April 13, 2015 by Jeff Shepard

Vicor Corporation today announced the expansion of its Picor Cool-Power™ ZVS Point of Load (POL) Regulator portfolio with the introduction of its new, high efficiency PI3749, PI3751, and PI3755 buck-boost regulators. By minimizing switching losses, Picor's ZVS topology enables efficiencies over 98% – maintains a high efficiency over the specified Vin range. High frequency operation (up to 2.5 MHz) claims best in class power density and transient response. Easy to use LGA System in Package (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. The PI3749 operates from 16 Vin to 34 Vin, regulates an output voltage from 12 V to 34 V and provides output current up to 11.5 A for power delivery over 200W. Power delivery can be further increased by using single wire current sharing without any additional components. This regulator is packaged in a 10x14x2.5mm LGA SiP module.

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 datacenter applications.

These dc-dc regulators enable 48 V direct to point of load powering when combined with VTM. The PI3751 and PI3755 are packaged in a 10x14x2.5mm and a 10x10x2.5mm LGA SiP module, respectively. The PI37XX series expands the portfolio of high performance, high density Picor Cool-Power ZVS POL Regulators. The entire Cool-Power portfolio is characterized by products that offer benchmark efficiency and density, and are simple to use, accelerating time to market.

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