New Advanced Bus Converter for High-Power Applications

Ericsson’s PKB4413DA is a low-profile, 408-W DC/DC converter module well suited for high-power, high-performance applications. Intended to provide point-of-load (POL) DC/DC converters with tightly regulated 12-V output at up to 34 A, the PKB4413DA’s five-pin, 1/8-brick footprint is compatible with the Distributed-power Open Standards Alliance’s (DOSA) standard. In addition, it has a full 36 to 75 V telecom input range. This combination makes it ideal for intermediate bus conversion in information and communication technologies (ICT) applications.Ericsson PKB4413DA
