The PKM 4000C series of high efficiency DC/DC converters are designed to provide high quality on-board power solutions in distributed power architectures used in Internetworking equipment in wireless and wired communications applications. The PKM 4000C series features a "double-p" footprint with dual output pins which reduces soldering losses to the board while increasing the cooling of the module. The PKM 4000C series uses patented synchronous rectification technology and achieves an efficiency up to 90% at full load. Included as standard features are output over-voltage protection, input under-voltage protection, over temperature protection, soft-start, output short circuit protection, remote sense, remote control, and output voltage adjust function. These converters are designed to meet high reliability requirements and are manufactured in highly automated manufacturing lines and meet world-class quality levels. Ericsson Power Modules is an ISO 9001/14001 certified supplier.
