阅读说明：本技术 用于吸收电流和源电流的转变器技术 (Converter techniques for sink and source currents ) 是由 赵汉良 于 2020-01-07 设计创作，主要内容包括：提供用于下沉和拉出功率级的技术。例如,功率级电路可包括：配置为耦合至第一输入电源轨的第一功率晶体管,配置为耦合至第二输入电源轨的第二功率晶体管,配置为耦合至负载并在第一和第二输入电源轨之间将第一功率晶体管与第二功率晶体管串联耦合的输出节点,和配置为在第一模式下操作第一和第二功率晶体管以向负载提供电流的控制器,且所述控制器在第二模式下操作第一和第二功率晶体管模式以从负载吸收电流。(Techniques for sinking and pulling power levels are provided. For example, the power stage circuit may include: the power supply circuit includes a first power transistor configured to be coupled to a first input power rail, a second power transistor configured to be coupled to a second input power rail, an output node configured to be coupled to a load and to couple the first power transistor in series with the second power transistor between the first and second input power rails, and a controller configured to operate the first and second power transistors in a first mode to provide current to the load, and the controller operates the first and second power transistor modes in a second mode to sink current from the load.)
