Data Sheet

36-75 Vdc Input, 50 A, 1.8 Vdc Output

The QmaX^TMSeries of high current single output DC/DC

converters from di/dt sets new standards for thermal per-

formance and power density in the quarter brick package.

The 50A QM48 converters of the QmaX^TMSeries provide

thermal performance in high temperature environments that

is comparable to or exceeds the industry’s leading 50A half

bricks. This is accomplished through the use of patent pend-

ing circuit, packaging and processing techniques to achieve

ultra-high efficiency, excellent thermal management and a

very low body profile.

QM48T50018 Converter

The QM48T50 converters have a power density more than

twice that of competitors’ 50A half bricks. Over 2 square

inches of board space can be saved for every slot in which a

50A half brick is replaced with a QM48T50 converter from

di/dt.

Features

•

Delivers up to 50 A @ 1.8 V (90 W)

Industry-standard quarter brick pinout

Higher current capability at 70ºC than most com-

petitors’ 50 A half bricks

Low body profile and the preclusion of heat sinks minimize

impedance to system airflow, thus enhancing cooling for

downstream devices. The use of 100% automation for as-

sembly, coupled with di/dt’s advanced electric and thermal

design, results in a product with extremely high reliability.

•

On-board input differential LC-filter

High efficiency – no heat sink required

Start up into pre-biased output

No minimum load required

Lowest profile in industry: 0.31” [7.9 mm]

Lowest weight in industry: 1.1 oz [31.5 g] typical

Meets Basic Insulation requirements of EN60950

Withstands 100 V input transient for 100 ms

Fixed frequency operation

Operating from a 36-75 V input, the QmaX^TMSeries con-

verters provide standard output voltage for 1.8 V. Output can

be trimmed from –20% to +10% of the nominal output volt-

age, thus providing outstanding design flexibility.

Fully protected

Remote output sense

Output voltage trim range: +10%/−20% with Industry-

standard trim equations

High reliability: MTBF of 2.6 million hours, calculated

per Telcordia TR-332, Method I Case 1

Positive or negative logic ON/OFF option

UL 60950 recognized in US and Canada and DEMKO

certified per IEC/EN 60950

Meets conducted emissions requirements of FCC

Class B and EN 55022 Class B with external filter

All materials meet UL94, V-0 flammability rating
