1 medium New DC-DC buck-boost regulators provide over 200W and over 98% peak efficiencyVicor has 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 minimising 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) 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, 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.

  • 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 200 W
  • 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.

  • Enables 48 V direct to point of load 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.
