摘要： A method for starting up a voltage-mode switching power supply into a biased load includes computing a ratio of the load voltage at the biased load to an input voltage of the switching power supply, generating a first signal indicative of the duty cycle of the voltage-mode switching power supply, comparing the first signal indicative of the duty cycle to the ratio, and turning on an output stage of the voltage-mode switching power supply only when the first signal indicative of the duty cycle is equal to the ratio. In this manner, the voltage-mode switching power supply can be started up to supply power to a biased load without dragging down the load voltage of the biased load.

摘要： There is provided a switching power supply device of hysteresis current mode control system which assures excellent response characteristic for change of output current and reduction of power consumption. In a switching regulator of hysteresis current mode control system, a sense resistor connected in series to a coil is eliminated, a serially connected resistor and a capacitor are connected in parallel to a coil in place of such sense resistor. Thereby, a potential of a connection node of these resistor and capacitor is inputted to a comparator circuit having the hysteresis characteristic for comparison with the reference voltage. Accordingly, a switch may be controlled for ON and OFF states.

摘要： A digitally-controlled, DC/DC converter includes at least one switched-mode power stage for the purpose of converting an input voltage (Vin) into an output voltage (Vout); the power stage including at least one controllable switching device, which is turned ON and OFF by a control device with temporal resolution Δt. The converter further includes a duty cycle control mechanism for controlling the duty cycle of the controllable switching device, the duty cycle control mechanism including a mechanism for estimating the output voltage error; a mechanism for estimating the target duty cycle; a duty cycle quantization mechanism for determining, for a target duty cycle estimate, a first set of quantized ON time/OFF time pairs suitable for controlling the switching device; and a selector mechanism for determining the turn ON and turn OFF times of said controllable switching device by choosing, cycle by cycle, an ON time/OFF time pair from a second set of quantized ON time/OFF time pairs, derived from said first set, choosing in such a manner that the amplitude of the output voltage error is continually minimized. To compensate for the load-dependent effects of parasitics, the second set of quantized ON time/OFF time pairs is adjusted continuously, to insure optimum performance at all load levels.

摘要： Circuits and methods to provide an LDO output stage implemented with low-voltage devices and still allowing higher voltage levels have been achieved. The output stage has been built using two low voltage MOS devices in series. During the time the regulator is in active mode the second MOS device acts as a small resistor in series to the pass device. During power down this second device actively protects the MOS pass device and itself from high voltage stress levels. This is achieved by a robust regulating mechanism that compensates leakage currents. These leakage currents normally determine the different potentials of the output stage during power down. Although the second transistor presents a resistive obstacle during active mode the total chip area required is smaller compared to a single pass device tolerating e.g. 5 Volts.

摘要： A method and circuit control the value of generated voltage derived from a supply voltage as the value of the supply voltage varies, such as during burn-in of an integrated circuit. A voltage generation circuit includes a generator circuit that receives a supply voltage and has a reference node and develops an output voltage from the supply voltage, the output voltage having a value that is a function of a reference voltage applied on the reference node. A coupling circuit receives the supply voltage and operates in response to a voltage control signal to vary an electronic coupling of the supply voltage to the reference node to thereby adjust the value of the reference voltage. A voltage sensing circuit develops the voltage control signal that is applied to the coupling circuit in response to the reference voltage.

摘要： As for a transistor, overlapped are factors such as a variation of a gate insulation film which occurs due to a difference of a manufacturing process and a substrate used and a variation of a crystalline state in a channel forming region and thereby, there occurs a variation of a threshold voltage and mobility of a transistor.This invention provides an electric circuit which used a rectification type device in which an electric current is generated only in a single direction, when an electric potential difference was applied to electrodes at both ends of the device. Then, the invention provides an electric circuit which utilized a fact that, when a signal voltage is inputted to one terminal of the rectification type device, an electric potential of the other terminal becomes an electric potential offset only by the threshold voltage of the rectification type device.
