摘要： The present invention is a voltage regulator circuit with enhanced frequency compensation. The voltage regulator includes an error amplifier, a dynamic bias circuit, an enhanced frequency compensation unit, a pass device and a compensation circuit. A signal from the pass device acts as an input signal of the error amplifier and is compared with another input signal, producing a differential signal. The differential signal is amplified and then provided to the dynamic circuit and the enhanced frequency compensation unit. The enhanced frequency compensation unit is provided such that a zero reference value in a left-hand plane can be generated to optimize the compensation for the voltage regulator circuit. The error amplifier includes a capacitor for compensating an output voltage of the voltage regulator circuit.

摘要： A four switch voltage converter is regulated for buck mode and boost mode under constant frequency valley-peak current mode control. Protection circuits are responsive to output voltage and regulator current to prevent excessive current that otherwise might result from abnormally low output voltage short circuit, or spurious switching abnormalities during low duty cycle operation. The regulator control circuit is responsive to the protection circuits to automatically connect a regulator inductor between a common potential and the output to limit current.

摘要： A disclosed amplifier and buffer circuit, for example for a linear voltage regulator, comprises an input gain stage, an integrator and a unity-gain output stage. An output stage compensation scheme enables stable operation over a broad range of output capacitance. For low to moderate output capacitance, the design of the output stage effectively pushes the output pole to high frequencies while an internal pole provided by the integrator is dominant and rolls off the gain at lower frequencies. For high output capacitance, an input impedance of the buffer couples the internal pole and output pole, such that the output pole becomes dominant while the internal pole gets pushed to higher frequencies, maintaining stability. This input impedance connection may utilize the base-emitter resistance of a bipolar junction transistor connected to the internal node, or the connection may use an MOS transistor and a separate RC circuit.

摘要： Systems and methods for regulating input to a sensor. A circuit receives an unregulated voltage signal and a reduced version of the unregulated voltage signal. These signals are regulated by separate regulators then compared. If the difference between the two regulated signals is greater than a threshold amount then no voltage signal is sent to an attached sensor. If the difference between the two regulated signals is less than a threshold amount then a regulated voltage signal is sent to the sensor.

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.

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.
