Abstract
A highly efficient, high control bandwidth and high-speed power supply with a linear driver and a switching regulator for regulating an output based on a control signal. The linear driver has a first input for receiving the control signal and a second input connected to the output for receiving negative feedback. The driver's output is controlled by its two inputs and has a capacitor connected in series with it to generate a capacitor voltage Vresponsive to the DC and low frequency components in the driver's output. The switching regulator has a control input and a regulator output connected in a regulator feedback loop. The control input receives capacitor voltage Vand the regulator feedback loop minimizes capacitor voltage V. Thus, switching regulator takes over the generation of DC and low frequency components, while the linear driver provides high frequency output current components.
