As a result, the HyperLight Load architecture delivers the best combination of efficiency and transient performance in the industry. This is extremely important as the market demands environmentally friendly energy efficient devices regardless of whether they are powered by a battery or AC adapter. One of the most common ways to improve energy efficiency is to ramp-up/down the performance of the core processor and other components as needed by the customer. As processor core and I/O voltages drop, maintaining tightly regulated supply rails to ensure reliable system operation becomes increasingly challenging under constantly fluctuating power demands.
