QME48T40018 数据手册

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.
