Flex Power Modules expands PKU-D analogue DC/DC converter series
The 16th brick isolated analogue DC/DC converter is claimed to deliver electrical and thermal performance and a price/performance ratio that is particularly attractive for telecomms.

Efficiency is typically 94.6% at Vin, 48V at full load. The DC/DC converter has an input voltage range of 36 to 75V, which meets the requirements of (European Telecom Standard) ETS 300 132-2 for normal input voltage range in -48 and -60V DC systems.

The output of up to 8.3A at 12V delivers 100W and there is output voltage trimming of up to 10%. Input to output isolation is 2,250V. Operating temperature range is  -40 to 125°C.

An optional baseplate is available for conduction cooling. This configuration maintains performance with no derating at 100°C, confirms the company.

The PKU4913D is supplied in an industry standard, low profile, 16th brick format, measuring 33.02 x 22.86 x 11.30mm (1.3 x 0.9 x 0.44 inches). Protection includes over-voltage, over-temperature and short-circuit mechanisms. Mean time between failures is 13.88 million hours.

The PKU4913D meets IEC/EN/UL 62368-1 safety standards.
