发明名称 POWER STAGE WITH SWITCHED MODE AMPLIFIER AND LINEAR AMPLIFIER
摘要 A method for producing an output voltage to a load may include, in a power stage comprising power converter having a power inductor, a plurality of switches arranged to sequentially operate in a plurality of switch configurations, and an output for producing the output voltage comprising a first output terminal and a second output terminal, controlling the linear amplifier to transfer electrical energy from the input source of the power stage to the load in accordance with one or more least significant bits of a digital input signal, and controlling the power converter in accordance with bits of the digital input signal other than the one or more least significant bits to sequentially apply switch configurations from the plurality of switch configurations to selectively activate or deactivate each of the plurality of switches in order to transfer electrical energy from the input source of the power stage to the load.
