Ericsson Launches the MacroDens DC/DC Power Module

September 21, 2000 by Jeff Shepard

Ericsson Microelectronics (Stockholm, Sweden) is introducing the MacroDens 13W PKF 4110B dc/dc power module, which offers a true component level on-board solution for a distributed power source for use in decentralized -48Vdc and -60Vdc power systems. The module's utilization of thick-film technology as well as its high degree of silicon integration makes it possible to achieve an MTBF figure of 4.9 million hours.

Ericsson claims that the combination of high reliability and the low stack height make the module particularly suitable for information technology and telecom applications, with board spacing down to 15mm. The modules are optimized for free convection cooling and have an operational ambient temperature range spanning between -45 degrees to 100 degrees C in compliance with present and future application needs, including non-temperature controlled environments.

Targeted at reducing board height and inventories, the PKF 4110B requires no heatsink to deliver the full 13W output across the input range. EMC compliance to EN55022 simplifies system level design, especially when combined with the remote control facility and 2ms ramp-up time.

All units go through burn-in and automated testing before shipping and are automatically trimmed to 3.3V. The output voltage is adjustable between 2.8V and 3.8V using a single resistor. The PKF family is of fully molded construction, making it compatible with aqueous and semi-aqueous cleaning, and is available packaged in tubes, Jedec trays and tape and reel. The construction and 20g weight ensure compatibility with pick-and-place assembly machines, and guarantee 0.1mm co-planarity.
