Abstract: Power management is an important criterion in today’s high efficiency mobile platform devices. As the technology of the mobile platform devicesadvances day by day, lots of techniques have been introduced for the efficient management of power on the mobile platform as well as to improve the battery life of the devices. This paper will present the implementation of the Power Management IC(PMIC) for power management on the Ultrabook platform and will feature the advantages of using PMIC for Ultrabook over the conventional Voltage Regulator Module (VRM) used for notebook like laptop. This paper will also highlight how the communication is done between the Embedded Controller (EC) and the PMIC in co-ordination with the multi-chip-package (MCP).
Keywords: Power Management Integrated Circuit (PMIC), Voltage Regulator Module (VRM), Voltage Regulator (VR), Embedded Controller (EC), Inter-Integrated Circuit (I2C).
