Digital PoL CMC converters design with high-frequency inductor current tracking

Inductor current tracking in high-frequency DC/DC converters is not effortless, especially when high output currents and low output voltages are demanded by the load. This paper proposes a guideline to design proper digital current-mode controlled (CMC) point-of-load (PoL) converts obtaining good accuracies in the inductor current tracking. The main idea is to obtain a equivalent voltage image of the inductor current which can be used for the digital controller to generate the converter control law. This strategy of measurement is generic and it has been validated in previous works. Thus, our experimental results validate the converter design process.
