This paper presents an integrated 6V to 1V, 3W DC-DC converter with a novel one-step dead-time digital controller designed for 40V 0.25μm CMOS technology. The proposed one-step digital control scheme can continuously optimize the dead-times for the turn-on and turn-off of the power MOSFETs. Comparing with previously reported dead-time optimization techniques, this work can achieve quick and accurate...
A fully integrated DC-DC converter with digitally controlled dual output stages is introduced in this paper. An auxiliary output stage is added in parallel to the main output switching stage to mitigate the trade-off between fast load transient response and high power conversion efficiency. A 12V-to-1V, 3W voltage-control-mode prototype converter is designed and fabricated with TSMC 0.25μm 40V process...
In this paper, the transistor sizing of an auxiliary output stage in a digitally controlled transient suppression system for fully integrated point-of-load (POL) DC-DC converters is investigated. The auxiliary output stage is added in parallel to the main output switching stage to help reduce output voltage deviation during load transient. The sizing of the auxiliary output stage in relation to the...
Fast load transient response and high power conversion efficiency in DC-DC converters have conflicting requirements on the size of the inductor. In this paper, an integrated point-of-load (POL) DC-DC converter with an smaller auxiliary output stage added in parallel to the main output switching stage to help reduce the output voltage deviation during load transient is investigated. The transistor...
