"The acquisition is the next logical step after our successful strategic product relationship with CHiL during the past year and will augment IR’s talent base by adding an experienced digital power design and applications engineering team."

CHiL Semiconductor CEO Ram Sudireddy said, "IR’s focus on power management solutions and energy efficiency make it an ideal partner for our customers and employees."

The transaction is expected to close in the first calendar quarter of 2011.
