Abstract
A method for improving heavy-to-light load transient response in low-power switch-mode power supplies is described. It uses a negative voltage input power rail and a digital controller with an extended duty ratio control value to provide faster discharging current slew rate in the switched mode power supplies (SMPS) inductor.
