The current company, Ericsson Power Modules AB, was formed as an autonomous company in 2002 when Ericsson Microelectronics was acquired by Infineon Technologies AG, Munich, Germany. The acquisition included Ericsson Microelectronics activities except its DC/DC power modules business that remained an independent company within the Ericsson group.

The company origins is Rifa that, as long as 1942 had the mission to manufacture resistors and capacitators for the Swedish radio industry during World War II. During 1947 it became fully owned by LM Ericsson. In 1988 the company name was changed to Ericsson Components and in 1999, when its power division, Energy Systems, was acquired by Emerson Electric Co, St. Louis, USA, it was changed to Ericsson Microelectronics.
