In this paper, a novel adaptive quasi-constant on-time current-mode control scheme is proposed and implemented in buck converters. While preserving the advantages of the conventional COT current-mode converters, this scheme allows fast transient response to step-load that is a critical requirement of a computer load with smart management. A small-signal model of the proposed circuit is also developed. Experimental results are also provided. This scheme is well suited for the next-generation dc converters for power management central-processor-unit devices. © 2016 IEEE. |
