摘要： A controller for a power converter includes a first amplification stage and a second amplification stage coupled to the first amplification stage. The first amplification stage generates a first amplified signal at a first terminal of an energy storage element according to an output signal the power converter. The second amplification stage generates a second amplified signal at a second terminal of the energy storage element and varies the second amplified signal in response to a change in the output signal. The second amplification stage further decreases the variation of the second amplified signal based on the first amplified signal.

摘要： A converter circuit includes a converter and a controller. The converter converts an input voltage to an output voltage. The controller receives a reference voltage, generates a slew voltage having a substantially constant first slew rate if the reference voltage changes from a first level to a second level, and controls the converter based on the slew voltage to cause the output voltage to change from a third level to a fourth level at a substantially constant second slew rate.

摘要： A controller includes an input selector, multiple cores and a multiplexer. The multiplexer is operable for multiplexing control signals to multiple output channels to provide multiple output signals. Each output channel can output a respective output signal, and each output signal represents a cyclic rotation of the control signals. The input selector is operable for enabling the cores to operate in a standby state alternately to control a multiplexing sequence of the control signals.

摘要： A power regulator for converting an input voltage to an output voltage includes a pass device, a reference signal circuit and an error amplifier. The pass device receives the input voltage and provides the output voltage at an output terminal of the power regulator. The reference signal circuit coupled to the output terminal is powered by the output voltage to provide a reference signal. The error amplifier coupled to the pass device is powered by the output voltage to compare the reference signal with a feedback signal indicative of the output voltage. The error amplifier can generate a control signal according to a result of the comparison to drive the pass device.

摘要： A circuit includes a first resistor, a second resistor, a voltage follower and a current mirror. The first resistor converts a current flowing through the first resistor to a voltage drop between positive and negative sides of the first resistor. The second resistor is coupled to the negative side of the first resistor. The voltage follower is coupled to the positive side of the first resistor via a non-inverting terminal, and coupled to the negative side of the first resistor through the second resistor via an inverting terminal to cause a voltage at the inverting terminal to follow a voltage at the non-inverting terminal. The current mirror is coupled to the voltage follower to provide a sensing current proportional to the current flowing through the first resistor.

摘要： A current sensing circuit includes a first resistor, a second resistor and a sense amplifier. The first resistor converts a current flowing through the first resistor to a voltage drop between positive and negative sides of the first resistor. The second resistor is coupled to the negative side of the first resistor. The sense amplifier is coupled to the positive side of the first resistor via a first pin of the sense amplifier, and coupled to the negative side of the first resistor through the second resistor via a second pin of the sense amplifier. The sense amplifier employs a negative feedback to generate a sensing current proportional to the current flowing through the first resistor.
