Advanced bus converter delivers up to 450W and 37.5A

December 14, 2016 // By Julien Happich
Ericsson has launched a low-profile, 450W DC/DC converter module that is designed to deliver a tightly regulated 12V output voltage at up to 37.5A to point-of-load (POL) DC/DC converters.

Offered in a 5-pin 1/8-brick footprint, compatible with the DOSA (Distributed-power Open Standards Alliance) standard, the new PKB4413D advanced bus converter has an input range from 36V to 60V and is suitable for intermediate bus conversion in ICT (Information and Communication Technologies) applications. The PKB4413D incorporates the company’s cutting-edge HRR (Hybrid Regulated Ratio) technology to deliver high-power conversion from a wide input voltage range, while keeping power losses low. Offering class-leading performance in thermally challenging environments and delivering a typical efficiency of 96%, with a 48V input and 12V output at half-load, the module significantly reduces energy and cooling costs. Competitive products typically dissipate 18% or more of their input power at 30A loads.

Designed to be through-hole mounted, the PKB4413D comes in the industry-standard eighth-brick format, measuring 58.4x22.7x13.2mm. Providing 1500V(dc) I/O isolation, the module also integrates a number of I/O protection and operational features, including: monotonic start-up and remote control as well as input under-voltage shutdown, output over-voltage, over-temperature and output short-circuit protection.
