摘要： System and method for a burst-mode switching voltage regulator with good stability and small output voltage ripple. A preferred embodiment comprises a current sense circuit coupled to a power switch in the burst-mode switching voltage regulator to sense a current flowing through the power switch. The sensed current can then be used (in conjunction with a feedback control signal that is based on the output voltage and is generated at the output of the burst-mode switching generator) to control the operation of the power switch to regulate the output voltage of the burst-mode switching voltage regulator. This enables the use of an output regulator with a small equivalent series resistance to minimize voltage ripple while providing good operational stability and fast transient response.

摘要： A system and method of provide real-time monitoring and control of a production environment. Manufacturing equipment having proprietary or non-standard digital interfaces provide a plurality of data streams having incompatible communication protocols that are converted to a common communication protocol by a translator and aggregated on a local area network. The resulting aggregated data stream is transmitted across an open network such as the internet or via a wide area network to a remote network. Virtual remote engineering of the production environment is possible from the remote network through monitoring, analysis and control of the production environment.
