A fast-transient voltage-mode hysteretic buck converter with digital-controlled power-drivingtracked-duration (PDTD) auxiliary current pump is proposed. The pump injection current duration is digitally controlled by the driving signal of the power stage. It aims at enhancing the transient response t...
