摘要： A comparing circuit and a control loop are used to maintain the peak level of current flowing through an inductor of a flyback converter. An inductor switch control signal controls an inductor switch through which the inductor current flows. The inductor current increases at a ramp-up rate during a ramp time and stops increasing at the end of the ramp time. The comparing circuit generates a timing signal that indicates a target time at which the inductor current would reach a predetermined current limit if the inductor current continued to increase at the ramp-up rate. The control loop then receives the timing signal and compares the target time to the end of the ramp time. The pulse width of the inductor switch control signal is increased when the target time occurs after the end of the ramp time. Adjusting the pulse width controls the peak of the inductor current.

摘要： A system involves LED strings and programmable current source circuits (CSC). An LED current flows through each LED string. Each LED current is controlled by an associated programmable CSC. In one embodiment, the CSCs form a chain. A first CSC uses a reference current for calibration, and thereafter supplies the reference current to the next CSC. When the next CSC detects the reference current, it uses the reference current for calibration. CSCs are calibrated one by one down the chain. In a second embodiment, each CSC can receive the reference current from a common conductor. If the common conductor is detected to be available, then the CSC uses the reference current for calibration. When the conductor is in use, the other CSCs detect the conductor as unavailable and do not attempt to self-calibrate. The CSCs use the reference current one by one, but in an order that changes over time.

摘要： Techniques for an adaptive synchronous switch in switching regulators are described, one aspect of which is to achieve a more optimal on/off timing of a synchronous switch that is controlled by the comparator in a feedback control loop and thereby improves power conversion efficiency and system performance; One approach samples a node in the output of the switching regulator and generates a sampled error signal that is analyzed to determine if the current comparator offset is too high or too low relative to a target switching regulator output value at least in part based on the sampled error signal value, and accordingly generates a compensated feedback error signal and applied to the compensated feedback error signal to an input of the comparator to have the effect of a comparator offset adjustment signal.

摘要： A combination brake light and radio antenna is disclosed. An elongated support structure includes a base for mounting to an automobile. At least one side wall of the device is made of a transparent or translucent material, such that lamps arranged in a linear array from the base to a top portion of the structure are visible from outside of the structure when the lamps are illuminated. A lamp driving circuit includes a power source and a switch for closing the circuit in response to a brake pedal of the automobile being depressed. The lamp driving circuit may illuminate the lamps in sequence, such as from bottom to top, for example, when the brake pedal is depressed. Further, the lamp driving circuit may illuminate the lamps at a brightness that is proportional to the pressure that is applied to the brake pedal, such that a relatively high application of pressure to the brake pedal results in the lamps being relatively brightly illuminated. An antenna wire from an appliance in the automobile is connected to the structure, which acts as an antenna in one embodiment.

摘要： An LED lamp includes a rectifier, an integrated circuit and a string of series-connected LEDs. The lamp receives an incoming AC signal such that a rectified version of the signal is present across the LED string. The integrated circuit includes a plurality of power switches. Each power switch is coupled so that it can separately and selectably short out a corresponding one of several groups of LEDs in the string. As the voltage across the string increases the integrated circuit controls the power switches such that the number of LEDs through which current flows increases, whereas as the voltage across the string decreases the integrated circuit controls the power switches such that the number of LEDs through which current flows decreases. LED string current flow is controlled and regulated to provide superior efficiency, reliability, anti-flicker, regulation against line voltage variations, power factor correction, and lamp over-voltage, over-current, and over-temperature protection.

摘要： A packaged device includes a first die, a second die, and specially spaced and positioned sets of package terminals. The first die includes a pulse-width modulator (PWM), a processor, a timer, high-side drivers, low-side drivers, and a fault protection circuit. The second die includes ultra-high voltage high-side drivers. In an ultra-high voltage application, the PWM and external circuitry together form a switching power supply that generates a high voltage. The high voltage powers external high-side transistors. The processor and timer control the ultra-high voltage high-side drivers, that in turn supply drive signals to the external high-side transistors through the package terminals. External low-side transistors are driven directly by low-side drivers of the first die. If the fault protection circuit detects an excessive current, then the fault protection circuit supplies a disable signal to high-side and low-side drivers of both dice. The disable signal is generated without execution of processor instructions.

摘要： A readily scalable modular progammable integrated circuit (IC) with improved power management is provided. An IC is described that contains one master controller module and a multiplicity of slave modules that include power-supplying functions, battery management functions, and analog and digital input-output functions. The master controller module configures the slave modules by writing data to the slave modules' configuration registers through the communication network. Each module contains a multiplicity of configuration registers that determine the module's operational and parametric characteristics. Programmability is achieved by configuring the modules to respond to appropriate signals on the configurable interconnection network.

摘要： A Multi-Tile Power Management Integrated Circuit (MTPMIC) includes tiles including an MCU/ADC tile and a power manager tile. The power manager tile includes a set of Configurable Switching Power Supply Pulse Width Modulator (CSPSPWM) components. These components, in combination with other circuitry external to the integrated circuit, are configurable to form a selected one of a number of different switching power supply circuits. Upon power up, an internal regulator supplies power to the CSPSPWM. The CSPSPWM then controls the power supply to begin switching in a low frequency start-up mode. The CSPSPWM determines during start-up the current sensing method based on circuitry external to the integrated circuit. A supply voltage generated is then supplied via a conductor of a standardized bus to a processor in the MCU/ADC tile. The processor begins executing instructions, and as a result writes across the standardized bus to configure the various tiles of the MTPMIC.
