Vicor Corp.'s V048K015T100 is the first 100A product in the company's V o I Chip line of voltage transformation modules (VTM) designed for "factorized power" architectures. At 400A per cubic inch, it also has the highest current-density. Bringing the speed and efficiency advantages of factorized power to isolated dc-dc topologies and point-of-load applications, the VTM responds to no-load-to-full-load conditions in less than a fraction of a microsecond for powering advanced microprocessor systems.

Optimized for low-voltage, high-current duties, it boasts an efficiency of 90 percent at 1.2V at 100A, and better than 92 percent at 50A. The VTM may be paralleled to deliver hundreds of amps at an output voltage that can be set from 0.8Vdc to 1.6Vdc.

The device is rated for a maximum continuous output of 100A at up to 1.5V out (26V to 55V input range). It can be operated either open-loop (for programmable low-voltage applications) or closed-loop (high regulation, compensates for the system's output resistance).

The V o I Chip's BGA package, with a profile of 0.40cm, supports in-board mounting. J-lead package options support on-board surface mounting (package profile as low as 0.64cm). The V048K015T100 is priced at less than 20 cents per amp in OEM quantities, and is available in JEDEC trays or tape and reel for automated pick-and-place and SMD assembly equipment.

Prototype quantities are already available.
