Abstract: A switch controller, an isolated system incorporating an integrated circuit (IC) and a method of operating a power switch. In one embodiment, the IC includes: (1) a monolithic substrate, (2) a drive circuit supported by the monolithic substrate and configured to drive a power switch, (3) a diagnostics block supported by the monolithic substrate and configured to provide diagnostic signals indicating at least one attribute associated with the power switch and (4) a control block supported by the monolithic substrate and configured to drive the drive circuit in response to control signals developed based on the diagnostic signals.

Abstract: Disclosed are advances in the arts with novel and useful current mode regulators. Circuits, systems, and methods for current mode regulation include a primary side for receiving an input signal and a secondary for outputting an output signal. A regulator spans the primary and secondary sides in a configuration by which the input signal may be rectified and thereafter provided to the output node as an output signal. A current monitor is provided at the output node for comparing the output signal to a reference. A communication link is included for providing feedback to the primary side of the regulator for use in regulating the signal.

Abstract: A system for power transfer is provided. In one exemplary embodiment, the system includes an inductive power device, such as a device that transmits or receives power over an inductive coupling. For example, an adjustable impedance is coupled to the inductive power device, where the adjustable impedance is used for dynamically controlling the power gain in the inductive power device, such as by damping power generated by circuit impedances, such as inductances, capacitances or resistances, and combinations thereof.

Abstract: The chopper stabilized amplifier circuit includes: an amplifier; a first current mirror coupled to an output of the amplifier through a first switch; a second current mirror coupled to the output of the amplifier through a second switch, wherein the first switch is operated out of phase with the second switch; and a summing node for combining currents from the first and second current mirrors.

Abstract: Systems, methods and circuits for sense circuit calibration. In one particular case, a system is provided that includes a sense circuit, a calibration circuit, and a sample and hold circuit. The sense circuit provides a sense current that is derived from either a reference current or a load current depending upon the operational state. The calibration circuit includes a calibration amplifier electrically coupled to the reference current and to the sense current. The calibration amplifier outputs a calibration signal representing a difference between the reference current and the sense current. The sample and hold circuit is operable to store a value representative of the calibration signal, and useful in forming a calibration offset current applied to the sense current.
