Flex launches DC-DC converters with a wide input range

Flex Power Modules has extended its PKB-D series of isolated eight-brick DC-DC converters with the launch of the PKB5213D.

This converter features a wide 18-60 V input range to include 24 V and 48 V nominal inputs, and a fully regulated 12 V output rated at 20 A/240 W. The part’s Isolation is 2250 VDC input to output, and is safety-rated according to IEC/EN/UL 62368-1.

Intended for power-dense applications in challenging environments such as robotics for example, the thermally-optimised PKB5213D is able to achieve 94.6% efficiency at 24 V input and 50% load, and has an MTBF figure of 10.6 million hours at 40°C, according to Telcordia SR-332.

Maximum hot-spot operating temperature is 125°C and an optional baseplate is offered for conduction cooled applications.

The PKB5213D is fully protected with an input under-voltage lockout, output over-voltage, short circuit and current limit as well as over-temperature protection. Output rise is monotonic and the part is able to start into pre-biased loads with a remote control also available.
