“…The operation of the buck converter is very simple; it alternates between connecting the inductor to source voltage to store energy in the inductor and discharging the inductor into the load. Moreover, a buck converter can obviously improve efficiency [3][4][5][6]. Traditional current-mode buck converter needs the slope compensation to ensure the system stability, when the duty cycle is greater than 50% [7][8][9].…”

SUMMARYA new fast-response buck converter using accelerated pulse-width-modulation techniques is proposed in this article. The benefits of the accelerated pulse-width-modulation technique is fast-transient response, simplecompensation design, and no requirement for slope compensation; furthermore, some power management problems are minimized, such as EMI (Electro Magnetic Interference), size, design complexity, and cost. The traditional voltage-mode speed is slower with the transient response, so an accelerated pulse-widthmodulation technique is used to solve the problem of slowed transient response in this article. The proposed buck converter has excellent conversion efficiency with a wide load conditions. The proposed buck converter has been fabricated with TSMC 0.35 mm CMOS 2P4M processes, and the total chip area is 1.32 Â 1.22 mm 2 . Maximum output current is 300 mA when the output voltage equals 1.8 V. When the supply voltage is 3.6 V, the output voltage can be 1-2.6 V. Maximum transient response is less than 5 ms. The simulation and experimental results are presented in this article.
