Abstract
This paper presents a dual-loop digital control approach for switching DC-DC converters. With an additional nonlinear control loop, the effect of inherent time delay of linear digital control loop on load transient response can be eliminated. Load transient response can be improved with reduced overshoot, undershoot and settling time. Simulation results based on a synchronous buck converter are shown to validate the proposed dual-loop digital control approachKeywords
