Applications

The Ericsson PKJ series are isolated half-brick DC/DC converter modules designed for use in distributed power architectures where a regulated intermediate bus voltage (typically 48V telecom bus) must be stepped down to a lower logic or processor supply rail. These modules are common in telecommunications equipment, networking hardware, industrial control systems, and embedded computing platforms where board-level power conversion is required. The half-brick format is an industry-standard package that mounts directly to a PCB via through-hole pins, making the PKJ 4111 API a drop-in solution for OEM designs and equipment service replacements requiring a 5V regulated output from a 36–72V DC source.
