AC-DC – PFC Universal Input

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.


The HAM module is a full-wave rectifier with a proprietary high-frequency zero-current switching (ZCS) boost converter providing up to 675 Watts of power in a package measuring only 2.4" x 4.6" x 0.5" (116.9 x 61 x 12.7 mm). The combination of the High-Boost HAM and our V375, VI-26x or VI-J6x DC-DC converters provides the power train
for a high-density, switching power supply meeting EN61000-3-2 requirements for harmonic current content with a power factor better than 0.99.



DC Filters – Input

The FIAM family of front-end modules provides EMI filtering, transient protection, and inrush current limiting in DC-DC applications, in a half-brick sized package. The 48 V
FIAM enables designers using Vicor's 48 Vin Maxi, Mini and Micro series DC-DC converters to meet the transient immunity and EMI requirements of Bellcore, FCC, ETSI, and European Norms. The Transportation/Railway FIAM modules (FIAM072 and FIAM110) are DC front-end modules designed for rail applications providing transient protection, inrush current limiting and EMI filtering.


  QPI Family
The Picor QuietPower QPI family of active EMI filters provides conducted common-mode (CM) and differential-mode (DM) attenation from 150 kHz to 30 MHz (CISPR22 range). The proprietary active filtering circuit provides superior attenuation at low frequencies intended to support EN Class B limits, including PICMG 3.0 for ATCA boards. In comparison to passive solutions, the use of active filtering reduces the volume of the common-mode choke, providing a low-profile, surface-mount device. Smaller size saves valuable board real estate and the reduced height enhances airflow in blade applications.



DC Converters – Isolated Regulated

  PRM and VTM
Factorized Power Architecture™ uses PRM buck-boost regulators and VTM current multipliers in a wide range of combinations to provide a complete isolated DC-DC power solution. The separate devices for optimized DC-DC conversion functions of regulation and isolation/transformation provide the highest degree of architectural flexibility of
design while facilitating time to market.


  Cool-Power ZVS Isolated DC-DC Converter
The Cool-Power family's very high-density isolated DC-DC converters are built on a proprietary ZVS topology using advanced control silicon integration, state-of-the-art planar magnetics and high-performance power semiconductor technology enabling high-switching frequencies.


  Maxi, Mini, Micro DC-DC Converters
The Maxi, Mini, Micro family of DC-DC converters provides high power density and low noise, with advanced power processing in a robust package. The converters are compact and efficient, and offer several input ranges, a variety of output voltages, enhanced output programmability, remote sense, and single-wire paralleling for high power or for true redundant operation. The efficiency and packaging design simplify thermal management with baseplate operation up to 100°C. The modules are available with five temperature grades, three baseplate styles, and six pin types. Maxi, Mini and Micro product series technology allows for the automated generation of user-defined designs without the customary long lead times typical of custom designs.



VI-200, VI-J00 DC-DC Converter
The VI-200 and VI-J00 series of DC-DC converters have set the standard for high power, low noise, reliability and ease-of-use in the component power industry. Thousands of combinations of input voltages, output voltages and power levels means not having to compromise when selecting modules for your power system. These power modules are field proven with an installed base of over 15 million units.




DC Converters – Non-Isolated Regulated – Buck

  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.



Power Path Management – Active ORings

The integrated Cool-ORing product takes advantage of two different technologies combining a 1.5 mΩ on-state resistance (RDS(on)sub>) single N-Channel MOSFET with high-density control circuitry. This combination provides superior density, minimizing PCB space to achieve an ideal ORing diode function, significantly reducing power
dissipation and eliminating the need for heat sinking, while minimizing design complexity.



Power Path Management – Load Switch


The Cool-Switch® PI2161 is a complete full-function load-disconnect switch solution for medium voltage applications with a high-speed electronic circuit breaker and a very
low on-state resistance MOSFET.

The PI2061 is a high-speed electronic circuit-breaker controller IC designed for use with the N-Channel MOSFETs in high-side load-disconnect switch solutions for medium
voltage applications.
