Description
The QME48T40 DC-DC Series of converters provide outstanding thermal performance in high temperature
environments. This performance is accomplished through the use of patented/patent-pending circuits, packaging,
and processing techniques to achieve ultra-high efficiency, excellent thermal management, and a low-body profile.
The 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 electronic circuits and thermal design, results in a product with extremely high reliability.
Operating from a 36-75 V input, the QME48T40 converters provide any standard output voltage from 3.3 V down
to 1.0 V that can be trimmed from –20% to +10% of the nominal output voltage (±10% for output voltages 1.2 V
and 1.0 V), thus providing outstanding design flexibility.
