摘要： A driver for a power converter, method of driving a switch thereof, and a power converter employing the same. In one embodiment, the driver includes switching circuitry referenced to a voltage level and configured to provide a drive signal for a switch referenced to another voltage level and subject to a control voltage limit. In a related, but alternative embodiment, the driver is employable with a power converter couplable to a source of electrical power adapted to provide an input voltage thereto. The power converter includes a power train having a switch referenced to the input voltage and subject to a control voltage limit. The driver includes switching circuitry referenced to a voltage level different from the input voltage and configured to provide a drive signal for the switch within the control voltage limit of the switch.

摘要： A controller for, related method of controlling a switch of, a power converter and a power converter employing the same. The controller is employable with a power converter including a switch of a power train configured to conduct for a duty cycle and provide a regulated output characteristic at an output thereof. In one embodiment, the controller includes a sparse analog-to-digital converter configured to determine a difference between the output characteristic and a desired characteristic and provide an error signal representing the difference in discrete steps. A magnitude of the discrete steps is small when the difference is small and the magnitude of the discrete steps is larger when the difference is larger. The controller also includes a duty cycle processor configured to provide a digital duty cycle signal to control the duty cycle of the switch as a function of the error signal.
