One way to mitigate the problem is to channel the power more efficiently. To achieve that goal, OEMs are incorporating a new class of power management integrated circuits, or PMICs, into the system. Generally, PMICs are analog/mixed-signal devices, which are designed to regulate and control the power in a system. In many respects, the power management IC is becoming just as critical, and possibly as complex, as their digital counterparts like the application processor and baseband.
