Abstract
A novel, simple DC-DC concept for low-power applications is presented. We propose a predictive peak-current mode controller in discontinuous conduction mode (DCM). The design is able to operate with a minimized output capacitor of only 27nF. Measurements shows low ripple voltage even at maximum load current steps and excellent transient response at a good DC control of Vout.
