TDK Innoveta Offers iEB/iQD Series Power Supplies

TDK Innoveta Inc. (Plano, TX) announced a pair of products aimed at emerging intermediate bus architectures. The iEB and iQD Series are part of the new FReta™ family of fixed-ratio power supplies, providing isolated “dc transformer” characteristics in standard footprint, high-density packages. The initial product offerings feature input ranges as wide as 42 V to 56 V, allowing more flexibility in selecting nominal input voltage. The first products in the family deliver a fixed-output ratio of four to one, or 12 V nominal from a 48 V input line. The FReta converters are suitable for reduced input range systems, such as servers, switches and routers. They provide an unregulated isolation stage with the highest density and efficiency, allowing them to establish a 12 V intermediate bus to power non-isolated, point-of-load (POL) converters.

The iQD product packs 300 W of power at currents up to 27 A into a standard quarter-brick footprint. The standard dimensions of 58 mm x 37 mm (2.28 in x 1.45 in) and pin location are complemented by a low-profile, 9.65 mm (0.38 in) design. The iQD products support parallel operation for added capability or expansion in high-power systems. The iEB offers 150 W in the same pin out as the iQD, but in more compact, one-eighth-brick standard packages of 58 mm x 23 mm (2.3 in x 0.9 in). Since POL converters demand constant power, not constant current, the iEB Series generates 150 W of constant power, at currents as high as 15.5 A. As a drop-in replacement for the iQD, it provides an option for cost reduction or size reduction as system power demands fluctuate. Suitable for the most aggressive card spacing, this smaller converter offers a profile of 8.5 mm (0.335 in).
