Variants added to DC/DC converter series

Flex Power Modules has expanded its range of 2-in x 1-in encapsulated, through-hole DC/DC converters with the addition of three new parts with single outputs of 24V (21.6-26.4V), 48V (43.2-52.8V) and 54V (48.6-59.4V). The parts retain the wide 8:1 input range of the PKE8000A series, suiting nominal inputs of 12V, 24V, 28V or 48V for a wide range of industrial, transportation, RFPA and IT applications.

Encapsulation of these power-dense converters provides mechanical protection and reliable operation in environments with high shock and vibration levels or with high dust/humidity.

An output power of 40W is available to high ambient temperatures with convection cooling, enabled by a design that maintains high conversion efficiency across the load and input voltage range. Maximum case operating temperature is 115°C with derating.

The PKE8000A series features 2250V input/output isolation rating according to IEC/UL 62368-1 and is fully protected against input overvoltage and output overload, short-circuit, over-voltage and over-temperature. A remote-control pin is provided along with voltage trim.

The footprint of the product is 2-in x 1-in (25.4mm x 50.8mm) and height is 0.47-in (11.9mm).

David Xie, Director R&D and Product Management, Shanghai, China of Flex Power Modules, says: “The ultra-wide input of our PKE8000A series enables users to stock just one part to cover a range of nominal inputs. The addition of more output variants extends their application even further including PoE applications needing a 54V supply for example”.
