The PKM 4000A series of DC/DC power modules represents another Ericsson "industry first" achievement in the continued development of our "third generation" of high density, high efficiency DC/DC power modules in an industry standard quarter brick package with unparalleled performance. The PKM 4910A PI module is a new addition to the series family with 76.2W/in 3 at 90% 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 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. Ericsson Inc., Microelectronics has been an ISO 9001 certified supplier since 1991.

S t r e s s in excess of Absolute Maximum Ratings may cause permanent damage. Absolute Maximum Ratings, sometimes referred to as "no destruction limits," are normally tested with one parameter at a time exceeding the limits of output data or electrical characteristics. If exposed to stress above these limits, function and performance may degrade in an unspecified manner.
