Vicor Corporation Expands Picor Isolated Cool-Power ZVS DC-DC Converter Module Line Up With New High Density (334 W/in³) Solutions

Complete module solutions are further enhanced when paired with Picor QuietPower active EMI filters for  use in demanding, space-constrained industrial and aerospace/defense applications

pr-isolated-coolpower.jpgAndover, MA – May 14, 2013 – Vicor Corporation (NASDAQ: VICR) today announced announced the expansion of its ultra high density Picor CoolPower® PI31xx series of isolated, ZVS-based DC-DC converters optimized for 24 V industrial, 28 V aerospace/defense and/or demanding wide temperature applications. The new Cool-Power PI31xx converters retain the product series’ signature 0.87" x 0.65" x 0.265" surface-mount package profile to provide up to 334 W/in3 power density and 2,250 V input to output isolation. At less than 50% the size of a conventional isolated 1/16th brick, Cool-Power PI31xx converters provide exceptional performance in an IC package for use in high density system designs.

Cool-Power PI31xx series converters utilize an advanced Zero-Voltage Switching (ZVS) architecture and 
high-performance planar magnetics to enable IC-like density and greater PCB layout flexibility in spaceconstrained environments. The high-switching frequency (900 kHz) of PI31xx series converters reduces 
input filter and output capacitance requirements, further reducing space constraints.
Fully equipped with a variety of programmable features, the PI31xx includes output voltage trimming, 
programmable soft-start capability, and remote on/off ENABLE. There is also a temperature monitor function,
providing an analog output voltage proportional to the internal module temperature.
The PI31xx is self-protected against fault conditions including: input over-voltage, under-voltage lockout, 
over-temperature, and output over-voltage protection. A constant current limit threshold is employed to 
protect against short circuit and overload conditions. All fault conditions have an auto-restart function.
When paired with 0.98" x 0.49" x 0.18" Picor QuietPower® EMI filters – the smallest filters in this product 
category at less than 25% the size of competing offerings – designers are afforded an end-to-end isolated 
DC-DC conversion and EMI filtering solution that’s unrivaled in density optimization. QuietPower filters
provide up to 99.5% efficiency and are designed for universal compatibility with high frequency switching 
DC-DC converters from any manufacturer. Example products include the QuietPower QPI-12 filter with high 
common-mode (>40dB) and high differential-mode (>70dB) attenuation for industrial applications. For 
aerospace/defense applications, the MQPI-18 offers >45dB and >75dB common-mode and differential-mode 
attenuation respectively.
“Used separately or in combination, Cool-Power PI31xx converters and QuietPower EMI filters defy the 
power density constraints of conventional converters and filters,” said Robert Gendron, Vice President, Picor 
Semiconductor Power Solutions, Vicor. “Together, they provide an elegant ‘two chip’ solution that makes it 
considerably easier to design for compact industrial, aerospace/defense, and/or demanding wide 
temperature applications.”
VIcor is showcasing its new Cool-Power PI31xx isolated DC-DC converters this week at PCIM 2013. 
Conference attendees can visit Vicor at Hall 9 Stand 155.
