The new Cool-Power PI31xx converters retain the product series’ signature 0.87 x 0.65 x 0.265 inch 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 claim to 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 space-constrained 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 inch Picor QuietPower EMI filters – the smallest filters in the 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 ( > 40 dB) and high differential-mode ( > 70 dB) attenuation for industrial applications. For aerospace/defense applications, the MQPI-18 offers > 45 dB and > 75 dB common-mode and differential-mode attenuation respectively.

Vicor is showcasing its new Cool-Power PI31xx isolated DC-DC converters at PCIM 2013 in Hall 9 on Stand 155.
