Rohm buys Irish digital power chip firm
Rohm has completed the acquisition of Irish power management IC developer Powervation for $70m.This a second acquisition for Rohm this year as it builds its power IC business on the back of its own core high voltage power semiconductor technology which includes the new “wonder technology” silicon carbide.
In May, Rohm bought Renesas’ 8-inch wafer fab in Shiga.The line will mainly make IGBTs, mosfets and piezoelectric MEMS on a 0.15μm process, and will be Rohm’s main site for power and MEMS.Rohm said it regards power and sensor devices as one of the four growth engines and is currently developing SiC, IGBT and MEMS products.The acquisition of Powervation, which is a spin-out of the University of Limerick, fits with this. It designs digital power controllers for cloud servers and communications infrastructure. This is a target market for Rohm.The Irish firm has developed a proprietary DSP control platform with patented xTune auto-tuning and ITM intelligent transient management technologies designed for complex multi-rail and multi-phase power systems.Rohm said it plans to combine the power management technology with its analogue/discrete power technologies.
