摘要:
Chip packages having power management integrated circuits are described. Power management integrated circuits can be combined with on-chip passive devices, and can provide voltage regulation, voltage conversion, dynamic voltage scaling, and battery management or charging. The on-chip passive devices can include inductors, capacitors, or resistors. Power management using a built-in voltage regulator or converter can provide for immediate adjustment of the voltage range to that which is needed. This improvement allows for easier control of electrical devices of different working voltages and decreases response time of electrical devices. Related fabrication techniques are described.
