The PKM 4318A PIOB module is a new addition to the PKM 4000A series family specifically for low voltage silicon devices in a one step conversion at 89% typical efficiency. These breakthrough features have been achieved by using the most advanced patented topology, ultilizing integrated magnetics and synchronous rectification on a low resistivity multilayer PCB. The product features fast dynamic response times and low output ripple, which are important parameters when supplying low voltage logics. The PKM 4000A series is especially suited for limited board E space and high dynamic load applications. Ericsson's PKM 4000A Power Modules address the converging "New Telecoms" market by specifying the input voltage range in accordance with ETSI specifications. Included in the PKM 4000A series are over-voltage protection, under voltage protection, over temperature protection, soft-start, short circuit protection, and industry standard output trim adjustment. The PKM 4000A Series also offers the flexibility of using an optional heatsink when needed, enabling reduced airflow, extended reliability, and higher ambient temperature operation. These modules are manufactured using highly automated manufacturing lines with a world-class quality commitment which is reflected in our standard five-year warranty.
