? efficiency typ 86% (5 v) at full load low profile 11.0 mm (0.43 in.) 1,500 v dc isolation voltage (duals = 1,000 vdc) mtbf >200 years at +75c case temperature rugged mechanical design and efficient thermal management, max +100 c case temperature emi measured according to en 55 022 and fcc part 15j the pkg series of dc/dc power modules are mem- bers of the eripower? range of low profile dc/dc converters for distributed power architectures in 48/60 vdc power systems. they provide up to 60w in single and dual output versions. utilizing the standard eripower? pka/pke pin-out with an even smaller footprint, the power density is 20 w/cu.in. the pkg units can be used as on-board distributed power modules, or serve as building blocks for more centralized power boards. the high efficiency makes it possible to operate over a wide temperature range without any extra heatsinks. at forced convection cooling >200 lfm (1 m/s), the pkg units can deliver full power without heatsinks up to +65c ambient. with derated output power it can also operate in pkg 4000 i 30?60 w dc/dc power modules 48 v input series temperature controlled environments with non-forced convection cooling. by adding external heatsinking, the temperature range can be extended even further. thanks to its peak power capa-bility, the pkg series is ideal for applications where max power is only required during short durations e.g. in disc drives. the pkg series uses ceramic sub-strates with plated copper in order to achieve good thermal manage- ment, low voltage drops, and a high efficiency. these products are manufactured using highly automated manufacturing lines with a world-class quality commitment and a five-year warranty. ericsson microelectronics ab has been an iso 9001 certified supplier since 1991. for a complete product program please reference the back cover.
