200W half-brick DC-DC provide 8:1 input range

Flex Power Modules expands its range of industrial DC-DC converters with the release of an ultra-wide input part covering 9-75VDC (80V/1s) with a selection of fully regulated outputs 12V, 24V, 48V or 54VDC, rated at 200W. The PKJ8200 series is in a baseplate-cooled industry-standard half-brick format with through-hole pins for board-mounted operation and provides up to 91% conversion efficiency. This permits operation from -40C to high ambient temperatures with a package limit of 110C. For example, full load is available to 80C ambient with no attached heatsinking with 3m/s airflow for the 12V output part.

The series has a significantly wide output adjustment range of -50%/+10%, settable by a single resistor, and full protection is included against input under-voltage, over-temperature, output over-current, over-voltage and short circuits. A remote sensing function and a primary-referenced remote shutdown pin are also supplied.

The series features 2250VDC input-output isolation (1500VDC input-baseplate and 1000VDC output-baseplate) and meets conducted EMC standards EN 55032, CISPR22 and FCC part 15J Class B with the specified external components.

The wide input range of the series makes the parts appropriate for demanding rail applications operating at nominal 24/36/48V inputs with the supply dips and surges as specified in railway standard EN50155. Shock and vibration levels specified in the standard are also fulfilled, along with the fire and smoke requirements in rail standard EN 45545-2.

David Xie, director of R&D and Product Management Shanghai, of Flex Power Modules, comments, “Our new PKJ8200 series, with its 8:1 input and wide output adjustment range, is ideal for rail and industrial applications where just one part can suit a variety of applications.”
