QM48T25050-NDC0 DC to DC Converter and Switching Regulator Module
The QM Series of high current single output dc-dc converters sets new standards for thermal performance and power density in the quarter-brick package.
The QM48T/S25050 converters of the QM Series provide thermal performance in high temperature environments that is comparable to or exceeds the industry’s leading 5 V half-bricks. This is accomplished through the use of patent pending circuit, packaging and processing techniques to achieve ultrahigh efficiency, excellent thermal management, and a very low body profile.
Low body profile and the preclusion of heat sinks minimize impedance to system airflow, thus enhancing cooling for both upstream and downstream devices. The use of 100% automation for assembly, coupled with advanced electric and thermal design, results in a product with extremely high reliability.
Operating from a 36-75 V input, the QM Series converters provide outputs that can be trimmed from –20% to +10% of the nominal output voltage, thus providing outstanding design flexibility.
