摘要： A switching regulator target voltage is adjusted to a first value corresponding to a pre-charge voltage that is present at a regulator output terminal. The switching regulator responds to a comparison signal resulting from a comparison of the target voltage and a feedback voltage. When the switching regulator is on, the target voltage is adjusted to a second value corresponding to a nominal regulator output voltage. In one embodiment, a synchronous switch is disabled when a lockout circuit receives a disable signal. The lockout circuit is unlocked when an enable signal is provided by a switching controller.

摘要： A voltage tripler which uses a charge pump with a single charge transfer capacitor to produce the required voltage is disclosed. The voltage tripler in conjunction with an inverter is useful for producing voltages with negative polarities. The voltage tripler when used in conjunction with a variable frequency oscillator circuit is useful in optimizing the power consumption by the charge pump of the voltage tripler when the tripler is not operating under load conditions. The tripler is useful in supplying power to a combination RS232 and RS422 or RS232 and RS485 interface, as well as other monolithic interface products.

摘要： A multiple channel analog to digital converter utilizing common conversion circuitry for converting multiple analog signals into corresponding digital signals. The converter includes an input stage having a plurality of capacitors, each one corresponding to one of the analog signals. The capacitors sample the respective analog signals and are successively coupled to common conversion circuitry, including a CDAC and a comparator. The CDAC iteratively increments or decrements the voltage of a selected one of the sampled analog signals for comparison to a reference voltage by the comparator. The comparator output is latched by a successive approximation register to provide a parallel output signal which is fed back to control the CDAC.

摘要： Charge pump circuitry is implemented using a voltage shifting technique to generate a symmetrical bipolar voltage. The symmetrical bipolar voltage charge pump power supply can be fabricated as an integrated circuit on a single substrate, and can be integrated with various interface circuits to provide symmetrical bipolar voltage thereto. The charge pump includes voltage shifting circuitry which generates an increased output voltage of a negative polarity and an increased output voltage of a positive polarity. The shifting circuitry is responsive to an internal oscillator which triggers charge accumulation and voltage shifting. Neither output voltage is generated from the other output voltage. Rather, the negative and positive supply voltages are each generated, in substantially the same manner, by charge transfer effected by the voltage shifting circuitry in response to triggering by the internal oscillator. Additional circuitry can be fabricated on a single substrate in combination with the presently disclosed charge pump to effect the optimum utilization of circuit board area while minimizing power consumption.

摘要： A voltage-to-time based windowed analog-to-digital converter (ADC) can have programmable reference voltage, conversion time, and accuracy of voltage regulation. The ADC can be fully implemented on a small silicon area and is suitable for implementation in various integrated digital controllers for high-frequency low-power switch-mode power supplies (SMPS). The programmable characteristics can be achieved through the utilization of the inherent averaging effect of the delay line or of the other voltage-to-time conversion structures and through the adjustments of delay cells' propagation times or the effective voltage-to-time conversion ratio in alternative structures.

摘要： A power sensor circuit including an input terminal, a switch, a nonlinear voltage drop element, and a switching unit, wherein the switching unit provides an output voltage. In response to a voltage difference between a first reference voltage and a second reference voltage, the power sensor circuit outputs a voltage that varies between two states. In one embodiment, the first state is substantially equal to the second reference voltage and the second state is substantially equal to ground. In another embodiment, the power sensor circuit is composed of four metal oxide semiconductor field effect transistors (MOSFETs) that compare a first reference voltage with a second reference voltage and determine whether the second reference voltage exceeds the first reference voltage by a predetermined voltage. If so, then the second reference voltage is produced at the output terminal of the power sensor circuit. Conversely, if the second reference voltage does not exceed the first reference voltage by the same predetermined level, then the output terminal is substantially at ground. The invention also relates to a method for generating a power sensing circuit.
