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.

The new PKB4413D advanced bus converter has an input range from 36V to 60V and is ideal for intermediate bus conversion in ICT (Information and Communication Technologies) applications.

Advanced design make it interesting for use in environments with high ambient temperatures or limited airflow.

The PKB4413D incorporates the company’s HRR (Hybrid Regulated Ratio) technology to deliver high-power conversion from a wide input voltage range, while keeping power losses low.

Offered in a 5-pin 1/8-brick footprint, PKB4413D offers up to 96% efficiency at 12V output and the compatibility with the DOSA (Distributed-power Open Standards Alliance) standard.

The device meets the safety requirements of IEC/EN/UL60950-1 and has a calculated MTBF of 8.5 million hours.
