Category: Electronics, Other Semiconductors, Vicor Corporation

Product Description

The VTM Current Multiplier VICOR V048F320T009 is a cutting-edge VI Chip® current multiplier that stands out for its speed, density, and efficiency. Designed for advanced power applications, it provides isolation from input to output, delivering up to 9.4 A of output current with a peak of 14.1 A for a millisecond, while maintaining a compact volume of less than 0.295 in³. Its nominal output voltage is 32 Vdc from a 48 Vdc input with a wide input range of 26 to 55 Vdc. The module operates efficiently with a typical efficiency rating of 96%, eliminating the need for output filtering.

Features and Performance

The module achieves a power density of 1017 W/in³, providing a significant capability within a small footprint – 260 W/in², and a light weight of 0.5 oz (15 g). Compatible with standard pick-and-place and surface mount assembly processes, it supports an operating temperature up to 125°C. Notable for its fast transient response, the VTM eliminates the need for bulk capacitance at the load, allowing for a decrease in system size while increasing reliability and reducing cost.

Operation and Compatibility

Capable of being used in parallel configurations for higher power needs, the module operates well across a wide output voltage range, adjustable from 17.3 to 36.7 Vdc. It features an open-loop operation where the output voltage tracks its input with a transformation ratio (K) of 2/3. For applications requiring tight load regulation, the module can be employed in a closed-loop system with an external regulator or DC-DC converter.

Absolute Maximum Ratings

The device withstands various voltage thresholds concerning input, output, and isolation voltage, with an isolation threshold up to 2,250 Vdc. The output current is rated at 9.4 A continuous, with a peak capability of 14 A for 100 ms. The output power ranges up to 337 W continuous with a peak of 506 W for a millisecond. It also provides a substantial thermal tolerance, allowing the case temperature during reflow to reach 245°C, suitable for modern soldering processes and storage or operating temperatures ranging from -65°C to 125°C.

Part Numbering System

The device’s part numbering system reflects its output voltage, current capabilities, and design configuration, indicating through-hole or surface-mount options along with product grade temperature ranges.
