Internet of Things (IoT) and wearable devices require small form factors, high efficiency and wireless connectivity. Conventional off-chip power management increases area and cost. 

Replacing off-chip power management with on-chip LDOs address the area and cost issues, but reduce system efficiency from 80% to less than 30% – more than tripling the wasted power in the system. 

There is a better way by designing Empower Integrated Voltage Regulators (IVRs) in the system, meeting all requirements for these applications simultaneously – lowest cost, smallest size and very high efficiency.
