Analogue DC/DC converters target telecoms applications Flex Power Modules has introduced the PKU4913D, the latest variant in its PKU-D series of analogue DC/DC converters in the sixteenth brick format.
The converter has been designed to deliver excellent electrical and thermal performance at an affordable cost.
Efficiency is high at typically 94.6% at Vin, 48 V at full load. Aimed primarily at telecoms applications, the converter has an input voltage range of 36 V to 75 V, which meets the requirements of the European Telecom Standard ETS 300 132-2 for normal input voltage range in -48 and -60 Vdc systems.
It provides an output of up to 8.3 A at 12 V, thus delivering 100 W, with output voltage trimming of up to 10%. Input to output isolation is 2250 V.
Quarter brick DC/DC converter can deliver 2450W peak power
Flex Power Modules has added to in its BMR491 series of high-density DC/DC converters with built-in digital interfaces.
The BMR491 converter can deliver 2450 W peak power for periods of up to one second, with a continuous output power rating of up to 1540 W, thus making it the highest power density digital DC/DC isolated converter available today.
It operates over an input voltage range of 48 V to 60 V and delivers a nominal 12 V output, making it suitable for data center applications. Efficiency is 97.5% at 48 Vin at half load, and the BMR491 can provide output current of up to 205 A.
