A novel lossless low-power current-sensing technique for current mode buck converter is presented in this paper. It adopts a lossless current-sensing method and a simple circuit topology current-sensing amplifier. The proposed technique can reduce the power of current-sensing circuit, which results in the static power optimization of current mode buck converter. Simulation results show that static power of the buck converter based on the proposed technique is 61.22mW, which is only 57.5% compared to the same converter with a typical current-sensing circuit.
