AC-DC Front Ends

  PFM
The PFM is the lowest profile AC-DC solution in the market. Vicor's VIA package enables designers to efficiently package power into their system's thermal management solution. Unlike the competition which offers solutions with twice the width and 3x the height, these slim line converters can do the same job in less space.

AC Input Front-End Module

  AIM
The AIM is an AC front-end module, which interfaces with worldwide AC mains. The AIM product line provides combinations of line rectification, EMI/RFI filtering, transient protection and inrush limiting to provide a non-isolated rectified AC line voltage in rugged, high density, low profile packages. When used in conjunction with Vicor’s DC-DC converters a universal AC input, high density, low profile power supply with outputs from 1 – 95 Vdc can be realized.

Switching Regulators – Non-Isolated Regulated

  Cool-Power ZVS Buck Regulator
The PI33xx/PI34xx integrates the controller, power switches, and support components all within a high-density, low-profile Land Grid Array (LGA) System-in-Package (SiP) offering low thermal and electrical impedance to the PC board. The PI33xx/PI34xx requires only an external inductor and minimal capacitors to form a complete DC-DC switching-mode buck regulator with no design or settings required for basic operation. The PI33xx also offers a rich feature set allowing for various power options including interleaving multiple buck regulators.
