Generating Greater System Efficiency for Single- to Multi-Cell Battery-Powered Designs

By: Eric Pittana and Sami Nijim

Abstract: Consumers want their electronics, including small, battery-powered devices, to operate for long periods between charges. The growing prevalence of devices powered by 1-, 2-, and 3-cell lithium-ion batteries has placed a spotlight on the importance of efficient power conversion in the power supplies for these applications’ hard-working processors. This white paper examines how dynamic power management capabilities in buck, or step-down, converters—key components of power supplies—can generate greater energy efficiency for the entire system. The paper also highlights how enhanced energy efficiency contributes to the extended battery runtime as well as battery life that consumers have come to expect from their electronic gadgets.
