摘要： A programmable error amplifier (PEA) that may be used as part of a voltage regulation subsystem to control the output of a digitally programmable voltage source is disclosed. According to various embodiments, the PEA comprises an amplification circuit, an analog voltage sampling circuit and a digital reference voltage sampling circuit. The amplification circuit may employ a negative feedback configuration, and include an amplifier and a plurality of feedback capacitors. The analog voltage sampling circuit is responsive to an analog input voltage (such as the output of the programmable voltage source) and is coupled to the amplification circuit. During a first operational phase (the sampling phase), the analog voltage sampling circuit stores a charge dependent upon the analog input voltage, and during a second operational phase (the conversion phase), the analog voltage sampling circuit transfers the charge to the feedback capacitors of the amplification circuit. The digital reference voltage sampling circuit is responsive to a digital programming word and also is coupled to the amplification circuit. During the first (sampling) phase, the digital reference voltage sampling circuit stores a charge dependent upon the digital programming word, and during the second (conversion) phase transfers the charge to the feedback capacitors of the amplification circuit. A differential voltage based on the difference between the analog voltage and a reference voltage determined by the digital programming word appears across the input terminals of the amplifier.

摘要： A power converter is disclosed. According to one embodiment, the power converter includes a first stage comprising a current source and a second stage comprising n output circuits for converting the current signal into n corresponding output voltages. Each of the n output circuits includes an output switch responsive to a corresponding nth control signal for regulating the corresponding nth output voltage. The second stage further comprises a controller for generating the n control signals. The controller includes, for each of the n output circuits, an error amplifier, a waveform generator, and a summing circuit. Each error amplifier is configured to generate an output signal based upon a comparison of the output voltage of the nth output circuit and a corresponding nth reference voltage. Each waveform generator generates a waveform signal. The waveform signals for the n output circuits are characterized by a common amplitude and period, and the phases of the waveforms signals are spaced at predetermined intervals. For each of the n outputs, the corresponding summing circuit sums the output of the error amplifier and the waveform signal to generate an amplitude-shifted waveform signal. The controller further includes a comparator for outputting the n control signals to the output switches based upon a comparison of the relative amplitudes of the amplitude-shifted waveform signals.

摘要： An AC-to-DC power converter (power supply) with high power factors and which minimizes the input charging current flowing through the separate inductor by locating the separate inductor between a full-bridge rectifier and the transformer but out of the storage capacitor's current path. In this manner, when the input voltage is sufficiently high, the converter draws input current into the transformer through the separate inductor, while current flowing to and charging the storage capacitor is unimpeded by the separate inductor. The current being drawn through the separate inductor and into the transformer may also be used to recharge the storage capacitor. Associated losses are reduced and the separate inductor may be reduced in size. Other embodiments eliminate the second primary winding in the transformer and place a second set of windings coupled to the separate inductor between the full-bridge rectifier and the storage capacitor, which reduces the current spike when the storage capacitor is recharged with current flowing through this path.
