This paper proposes a new method to improve the efficiency of boost converter under light load conditions by using the hybrid modulation of hysteresis current mode and burst mode (HCM-BM). A circuit is designed to satisfy the requirement of adaptive fast switching between HCM and BM. The whole circuit of proposed HCM-BM converter and conventional HCM converter have been built with a standard 0.18-µm CMOS process, respectively. The simulation results show that the proposed converter provides a maximum efficiency improvement of 17% under light load compared with the conventional boost converter. Meantime, it can achieve up to 74% efficiency at 10 µA load.
