PMIC (Power Management ICs)

All power supplies required by the system are provided Power Management ICs BD9594AMWV/BD9591AMWV

The BD9591AMWV and BD9594AMWV system power management ICs supplies power to the main system blocks, including the CPU, IOH, clock IC and DDR2 memory. A complicated supply sequency controller is also built in, eliminating the need for a special power supply control IC while enabling configuration of an optimized system power supply and environment for the Intel® Atom™ E600 Series processor.

 Features
  • Complicated power supply sequence (which conventionally was performed via microcontroller) is built in, reducing user design load.
  • System-optimized efficient power supply design requires only a single FET for greater compactness.
  • Used in conjunction with an BU7335MWV CGIC provides additional platform support.
