摘要： A lower-cost and more precise control methodology of regulating the output voltage of a Flyback converter from the primary side is provided, which works accurately in either continuous voltage mode (CCM) or discontinuous mode (DCM). The methodology can be applied to most small, medium and high power applications such as cell phone chargers, power management in desktop computers and networking equipment, and, generally, to a wide spectrum of power management applications. Two highly integrated semiconductor chips based on this control methodology are also described that require very few components to build a constant voltage Flyback converter.

摘要： A primary-side regulation (PSR) controller integrated circuit includes a PSR CC/CV controller and a non-volatile shift register. An assembled power supply that includes the integrated circuit is in-circuit tested to determine errors in power supply output voltage and/or current. Programming information is determined and shifted into the shift register. During programming, the power supply regulates to a different output voltage, and the different voltage is used for shift register programming. After programming, the power supply operates in a normal mode so that the output voltage and current are within specification. The voltage and current to which the power supply regulates are set by some of the bits of the programming information. Other of the bits set error correction circuits of the PSR CC/CV controller such as a primary inductance variation compensation circuit, a line input voltage variation compensation circuit, an efficiency variation compensation circuit, and a cord resistance compensation circuit.

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 start-up time accelerator is described for a switch controller that controls turning on or off a switch in a switching regulator. The start-up time accelerator uses the switch as a current amplifier and provides the amplified current to a capacitor using a current amplification path. In one example, the capacitor provides the bias voltage to a switch controller for the switch. Providing an amplified current to the capacitor accelerates the rate at which the bias voltage increases and reduces the time until the bias voltage reaches the turn-on threshold voltage of the switch controller. After the turn-on threshold voltage of the switch controller is reached, a second path is enabled for current to and from the capacitor and the capacitor provides the bias voltage to the switch controller until a voltage from an output voltage terminal is sufficiently high to provide the bias voltage for the switch controller through an auxiliary winding of a transformer.

摘要： An integrated circuit includes a plurality of tiles. One tile is a master tile. Other tiles contain writable registers of memory structures. Information for configuring circuitry of the tile is stored in the register in the tile. An individual one of the registers can be written via the master tile. Each memory structure of a register includes a non-volatile floating gate cell (that stores the configuration information) as well as a volatile cell. All transistors have the same gate insulator thickness. Although a programming pulse signal is applied to all memory structures, the state of the non-volatile cell of a memory structure is only changed if the state stored by the associated non-volatile cell differs from the state stored by the volatile cell. Floating gates are automatically refreshed by the programming pulse signal. By storing configuration information in each tile, inefficiencies associated with using blocks of non-volatile memory are avoided.

摘要： An integrated circuit (IC) and fabrication method thereof is provided that include the steps of specifying a plurality of required tile modules suitable for a particular end application, each of the modular tiles being configured to perform a predetermined function and constructed to have approximately the same length and width dimensions. The modular tiles are used to form the IC in a standard IC fabrication process. In many implementations, physical layout of the IC does not include the step of routing. Capabilities also include configuring the modular tiles to have programmable performance parameters and configuring the modular tiles to cooperate usefully with one another based on a programmable parameter.
