(Telecompaper) German chipmaker Dialog Semiconductor adjusted its full-year revenue expectations downward by 5 percent after learning that Apple planned to reduce the share of main power management chips (PMICs) it sources from Dialog for its 2018 smartphone platform. Apple will source PMICs from two suppliers instead of just from Dialog for one of its three new iPhone models this year. It's the first time Dialog's custom PMICs will be dual sourced, said Dialog. The company said in a statement it still expects to see revenue growth in 2018, with revenue performance "strongly weighted" towards the second half of the year.
