Vicor Corporation expands its Picor Cool-Power Portfolio
Vicor Corporation has announced the expansion of its ultra-high density Picor Cool-Power 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/in 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.
The Cool-Power PI31xx series converters can utilize a Zero-Voltage Switching (ZVS) architecture and high-performance planar magnetics to enable IC-like density and greater PCB layout flexibility in space-constrained environments. They also comprise of high-switching frequency (900 kHz) which help to reduce input filter and output capacitance requirements.
The other features of PI31xx converters include output voltage trimming, programmable soft-start capability, temperature monitor function and remote on/off ENABLE. They are self-protected against fault conditions including input over-voltage, under-voltage lockout, over-temperature, and output over-voltage protection.
Robert Gendron, Vice-President, Picor Semiconductor Power Solutions, Vicor, said, "Used separately or in combination, Cool-Power PI31xx converters and QuietPower EMI filters defy the power density constraints of conventional converters and filters. 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."
Picor Cool-Power PI31xx isolated DC-DC converters for OEM quantities are available at $37.40 for I-grade (-40°C to 125°C) and $89.76 for M-grade (-55°C to 125°C) devices.
