The new 38 A SQT48 eighth-brick Intermediate Bus Converter (IBC) provides an ultra-high efficiency single output that is only 62% the size of the industry-standard quarter-brick IBC, while still preserving the same pinout and functionality. Inclusion of this converter in a new design can result in significant board space and cost savings.
Operating from a 38 to 55 VDC input, the SQT48T38096 IBC provides a 5:1 fixed ratio, isolated, step-down voltage. Output voltage is directly proportional to input voltage with a conversion ratio of 5:1 at 48 VDC; the resulting output voltage would be 9.6 VDC. The converter has paralleling capability with accurate current sharing.
The 38A SQT48 IBC provides outstanding thermal performance in high temperature environments. This performance is accomplished through the use of patented/patent-pending power electronic circuits, packaging, and processing techniques to achieve ultra-high efficiency, excellent thermal management, and a low-body profile.
The designer can expect system reliability improvements over other available converters because of the 38A SQT48 IBC’s optimized thermal efficiency which is due to the use of a multi-layer PWB and the extensive use of heavy copper plating. The low-body profile minimizes airflow shadowing, thus enhancing cooling for both upstream and downstream devices. The use of 100% automation for assembly, coupled with advanced electronic circuits and thermal design, results in a product with extremely high reliability. |
