PKM4000A Datasheet | Ericsson Microelectronics

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 such as demanding microprocessors. Ericsson's PKM 4000A Power Modules address the converging "New Teles" market by specifying the input voltage range in accordance with ETSI specifications. The PKM 4000A series also offers over-voltage protection, under voltage protection, over temperature protection, soft-start, and is short circuit proof. These modules are manufactured using highly automated manufacturing lines with a world-class quality mitment and a five-year warranty. Ericsson Inc., Microelectronics has been an ISO 9001 certified supplier since 1991. For a plete product program please reference the back cover.
