Analogue DC/DC Converters for Superior Price/ Performance Ratio in Telecom Applications

PKU4913D, the new PKU-D analogue DC/DC converter from Flex Power Modules in the sixteenth brick format delivers excellent electrical and thermal performance at an affordable cost.  The efficiency of this device is 94.6% at Vin, 48 V at full load and an input voltage range is 36 V to 75 V and it meets the requirements of the European Telecom Standard ETS 300 132-2 for normal input voltage range in -48 and -60 Vdc systems.

This converter 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. Suitable to be used in telecoms applications, these converters come with an optional baseplate, with cooling achieved mainly by conduction through a cold wall. This can maintain the performance of the converter with no derating at 100°C.

The PKU4913D measures 33.02 x 22.86 x 11.30 mm (1.3 x 0.9 x 0.44 in and it includes sophisticated over-voltage, over-temperature, and short-circuit protection mechanisms, which increases reliability and operational lifespan. The mean time of the converter is between failures of 13.88 million hours. The devices have an operating temperature range of -40°C to +125°C. This converter meets safety standards according to IEC/EN/UL 62368-1. The PKU4913D is now available for purchase from the company website.
