      Power
      AC Adapter
      • CS-II 90W AC Adapter for Discrete Gfx Models
      • CS-II 65W AC Adapter for Integrated Gfx Models
      London/Berlin has Max Power Control function for critical high power situation which is implemented by EC F/W and Charger IC via SMBus.
      The circuit detects trigger point according to the appropriate threshold below.
      The design is different between Discrete model and Integrated model because integrated model supports 65W AC only.
