Vicor has expanded its ultra high density Picor Cool-Power® PI31xx series of isolated, ZVS-based DC-DC converters optimized for 24V industrial, 28V 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.
Utilising advanced Zero-Voltage Switching (ZVS) architecture and high-performance planar magnetics, 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.
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 optimisation. 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.
