摘要: | an authentic mode-toggled detector (AMTD) technique is proposed to achieve load and line regulations in a proposed buck-boost (BB) converter. In the case of load transient, conventional BB converter will oscillate and cannot settle to a well-regulated output voltage owing to the on-resistance of the power MOSFETs. Accurate and expeditious mode-toggled detection in the BB converter meet the requirements of load and line transient response by means of the proposed adaptively near-immediate freezer (ANIF) technique. Besides, due to pulse frequency modulation (PFM) implemented in the proposed BB converter, ultra wide load range from 10mA to 900mA can have high efficiency from 80% to 95%. Simulation results show the proposed BB converter fabricated in VIS 0.25 mu m process can be well-regulated under the input voltage ranging from 2.7V to 4.2V. |
