Flex Power adds eighth brick DC-DC
PKB-D series of isolated DC-DCs provides 240W from a wide input range
Flex Power Modules has extended its PKB-D series of isolated eighth-brick DC-DC converters with the launch of the PKB5213D, featuring 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. Ideal for power-dense applications in challenging environments such as robotics for example, the thermally-optimised PKB5213D achieves 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. 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.
