A switched mode assisted linear (SMAL) amplifier/regulator architecture can be configured to supply regulated power to a dynamic load, such as an RF power amplifier. Embodiments of a SMAL regulator can include a linear amplifier and a switched mode converter parallel coupled at a supply node, and configured such that the amplifier sets load voltage, while the amplifier and the switched converter are cooperatively controlled to supply load current. The amplifier can include separate feedback loops: an external relatively lower speed feedback loop for controlling signal path bandwidth, and an internal relatively higher speed feedback loop for controlling output impedance bandwidth of the linear amplifier. The linear amplifier can be AC coupled to the supply node, and the switched converter can be configured with a capacitive charge control loop that controls the switched converter to effectively control the amplifier to provide capacitive charge control.
