FCC and EN55022 when used with external filter

• All materials meet UL94, V-0 flammability rating

Description

The QmaX^TMSeries of high current single output dc-dc converters set new standards for thermal performance and

power density in the quarter-brick package.

The 45 A QM48 converters of the QmaX^TMSeries provide outstanding thermal performance in high temperature

environments that is comparable to or exceeds the industry’s leading 50 A half-bricks. This performance is

accomplished through the use of patented/patent-pending circuit, packaging, and processing techniques to

achieve ultra-high efficiency, excellent thermal management, and a very 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 QmaX^TMSeries converters provide any standard output voltage from 3.3 V

down to 1.0 V. Outputs 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.
