Abstract
A novel standby mode scheme with light load efficiency improvement is proposed in this paper, which is especially suitable for modern boost dc-dc converters powered by Li-ion battery. The proposed output load estimator is able to accurately reflect the output load current under light load condition once inductor current enters in the discontinuous conduction mode (DCM). Our experimental results show that the proposed boost dc-dc converter can automatically select approximate PWM switching frequency according to the detected information of the proposed output load estimator, regardless of power supply and inductor value.
