摘要： An amplitude limiter circuit includes an inductor and a shunt circuit. The inductor has a first terminal connected to an input node. The shunt circuit is connected to a second terminal of the inductor and also is connected to a low impedance node. If an overvoltage condition forms on the input node, the shunt circuit forms an overvoltage current path from the input node, through the inductor, through the shunt circuit and to low impedance node.

摘要： A circuit, system, and method for tracking energy use in a electronic circuit. A circuit includes a DC-DC converter and a comparator. The DC-DC converter is configured to maintain a desired output voltage by switching energy to an energy storage device based on an output voltage of the energy storage device. The DC-DC converter includes an output driver configured to source current to the energy storage device. The comparator is coupled to the DC-DC converter. The comparator is configured to identify a drive state of the output driver, and to generate a signal indicative of amount of energy transferred from the DC-DC converter to a load circuit. The signal corresponds to the identified drive state.

摘要： A long-range power-efficient multiple-band identification system and method includes, for example, a base-station control module and paired electronic key fob. The base-station control module and paired electronic key fob is arranged to provide a UHF (ultra-high frequency) wake transmitter for transmitting a wakeup signal in a UHF frequency range to the paired electronic key. When in range, the electronic key is awakened by the wakeup signal and in response transmits an acknowledgment reply to the base-station control module. After receiving the acknowledgment, the base-station control module transmits a relatively high power localization signal for determining an electronic key location.

摘要： A power conversion system includes a maximum load current controller that is operable to limit a load current. For example, in a power conversion system operating in a discontinuous conduction mode (DCM), the maximum load current controller limits the load current by determining an idle period in an active cycle for power switches of the maximum load current controller. The maximum load current controller is optionally operable to approximate values for the time idle period that are substantially equal to theoretically calculated values.

摘要： A power-gated electronic device and a method of operating the same is provided. The power-gated electronic device comprises a low drop out voltage power supply (LDO), an auxiliary power supply and at least one electronic domain having a power gate. The LDO provides a supply voltage to the at least one electronic domain which is coupled to a supply rail of the LDO via a switch, acting as a power gate. The auxiliary power supply comprises at least one current source which is coupled to the electronic domain via an auxiliary switch acting as an auxiliary power gate. The auxiliary power supply is configured to control the auxiliary switch as a function of a voltage difference between a reference voltage and the auxiliary supply voltage.

摘要： A DCDC converter includes a controller, an up/down counter, a first power stage and a second power stage. The controller generates an up/down control signal. The up/down counter generates a first power stage control signal and a second power stage control signal based on the up/down control signal. The first power stage generates a first output current at a first phase and at a first voltage based on the first power stage control signal. The second power stage generates a second output current at a second phase based on the second power stage control signal. The up/down counter modifies the first power stage control signal to control the first power stage such that the first output current attenuates from a first power stage output to a secondary first power stage output. The controller can further output a control signal to modify the first voltage of the first power stage.

摘要： A mixed signal approach is applied to detect an output voltage condition as applied to a load. A current mode monitoring approach can be adopted and applied in discrete time using a mixed analog and digital approach. For application to various low drop-out voltage regulator situations, a sensing transistor can be connected in parallel with a feedback loop transistor of the low drop-out voltage regulator circuit to create a sensing current that is proportional to the current passing through the feedback loop transistor and thus the output current provided to the load. This sensing approach can be adapted to sense both overload and light load conditions to allow dynamic power control of the device.
