A Fast Transient Current-Mode Buck Converter With Linear Regulation Mode

Pang-Jung Liu et al.

Summary: This article proposes a configurable supply mechanism in the power stage to simultaneously improve the load transient response and power conversion efficiency. The proposed mechanism consists of a DC-DC converter and an auxiliary power circuit (APC) which can adapt to variable load conditions. The APC provides additional charging or discharging current to compensate for any differences between the load current and inductor current during step-load changes, and two auxiliary transient transistors are employed to adjust the output level of the error amplifier. Experimental results show significant improvements in recovery time and efficiency with the proposed method.
