DC/DC converter offers excellent thermal management

Ericsson has launched a low-profile, 12V-output, digital DC/DC converter module that offers up to 25A current handling and 300W of power to deliver tightly regulated voltages to POL DC/DC regulators. Compatible with the DOSA (Distributed-power Open Standards Alliance) 5-pin eighth-brick footprint standard and offering an input range from 36V to 75V, the PKB4313D suits intermediate bus conversion in ICT applications.

Offering excellent thermal capabilities, the new high-power module employs Ericsson’s leading-edge HRR technology to deliver high-power conversion across a wide input voltage range, while keeping power losses low. Combined, all these factors have resulted in a module that delivers high-efficiency power conversion with exemplary performance in thermally challenging environments. Delivering a typical efficiency that exceeds 96% with a 48V input and 12V output at half-load, the module also offers significantly reduced energy and cooling costs. Competitive products will typically dissipate 15% or more power at full load than the PKB4313D.

Martin Hägerdal, President, Ericsson Power Modules, says: “The new PKB4313D is the first in a new series of high-power advanced intermediate bus converters from Ericsson. The module combines the company’s innovative HRR topology, which has been further enhanced for this new series, together with world-class power efficiency, tightly regulated voltage capabilities and best-in-class thermal handling characteristics. Overall, the new product offers a compelling package that delivers significant competitive advantage to customers operating at the cutting edge in a range of telecom, networking and industrial applications.”
