Find out how to make accurate low power mode measurements to get the highest efficiencies. Overall system efficiency is a critical design parameter in battery powered systems. It affects both the battery capacity requirement and the end product's run time. Proper system efficiency and run time calculations can be achieved only when the power supply's efficiency measurements are accurate. Most battery powered systems take advantage of a power supply feature called pulse frequency modulation (PFM) to improve power supply efficiency at light loads. The same characteristics that help PFM mode achieve high power supply efficiencies also create several challenges for properly measuring the efficiency....more  (0) Comments
