PKJ 4418 PIOAT/PKJ 4318 PIOAT/PKJ 4218 PIOAT Advanced Specification 15-30A DC/DC Power Modules 48V Input, 1.5V Output * * * * * * High efficiency 87% Typ (15A) at full load Industry standard footprint Max case temperature +100C Wide input voltage range according to ETSI specifications 1,500 Vdc isolation voltage MTBF > 3 million hours in accordance with Bellcore TR-332 The PKJ series represents a "third generation" of High Density DC/DC Power Modules providing high efficiencies. To achieve this high efficiency, Ericsson uses proprietary drive and control circuits with planar magnetics and low resistivity multilayer PCB technology, and a patent pending topology with active rectification. The PKJ series can be used without bulky and height consuming heatsinks, resulting in a lower total cost. This also provides narrow board spacing for electronic, shelf based applications. The PKJ series also offers the flexibility of using a heatsink when needed, enabling reduced airflow, extended reliability or higher ambient temperature operation in a wide range of 48V and 60V DC powered systems. Similar to other Ericsson Power Modules, the PKJ series includes an undervoltage shut down facility, protecting the associated batteries from being too deeply discharged. The PKJ series also offers over-voltage protection, over-temperature protection and is short circuit proof. The products are in the industry standard package size and offer a beneficial alternative to competing products on the market. Because for certain applications they may not require heatsinks, they are ideal for cost sensitive or highdensity applications. These products are manufactured using highly automated manufacturing lines with a world-class quality commitment and a five-year warranty. Ericsson Microelectronics has been an ISO 9001 certified supplier since 1991. For product program please see back cover.
