摘要： A controller for controlling operation of a switching regulator including a modulator, a discontinuous conduction mode (DCM) controller, an audible DCM (ADCM) controller, and a sub-sonic discontinuous conduction mode (SBDCM) controller. The modulator generally operates in a continuous conduction mode. The DCM controller modifies operation to DCM during low loads. The ADCM controller detects when the switching frequency is less than a super-sonic frequency threshold and modifies operation to maintain the switching frequency at a super-sonic frequency level. The SBDCM controller detects a sub-sonic operating condition during ADCM operation and responsively inhibits operation of the ADCM mode controller to allow a SBDCM mode within a sub-sonic switching frequency range. The SBDCM operating mode allows for efficient connected standby operation. The SBDCM controller allows operation to return to other modes when the switching frequency increases above the sub-sonic level.

摘要： A current mode control regulator including a control circuit and a current generator. The control circuit regulates an output voltage based on a reference voltage using current mode control. The current generator applies an adjust current to a feedback current signal, in which the adjust current is proportional to a difference between a voltage indicative of the output voltage and the reference voltage to emulate an AC load resistance at an output of the current mode regulator. A load resistor emulator emulates an AC load resistor to increase the phase margin of current mode control regulator when operating without a battery coupled to the output, such as when the battery is physically removed or otherwise electrically disconnected. Operation is not substantially changed when the battery is connected, so that the desired phase margin is achieve with or without the battery.

摘要： An apparatus including a proportional gain circuit, an integral gain circuit, a limit circuit, a gain booster circuit and a combiner. The gain circuits apply a proportional gain and an integral gain to an error signal, and the combiner combines both gained error signals to provide a control signal. The limit circuit applies a limit function that limits the proportional gain to a magnitude. The gain booster circuit increases gain while the limit function is being applied. The increased gain may be applied to only the integral gain, or to both the integral and proportional gains such as by boosting gain of the error signal. The apparatus may be a regulator that may include multiple control loops providing multiple error signals, in which a mode selector selects one of the error signals to control regulation. The limit function increases stability while the boosted gain improves transient response during mode transitions.

摘要： A hysteretic current mode buck-boost voltage regulator including a buck-boost voltage converter, a switching controller, a window circuit, a ramp circuit, and a timing circuit. The timing circuit may be additional ramp circuits. The voltage converter is toggled between first and second switching states during a boost mode, is toggled between third and fourth switching states during a buck mode, and is sequentially cycled through each switching state during a buck-boost mode. The ramp circuit develops a ramp voltage that simulates current through the voltage converter, and switching is determined using the ramp voltage compared with window voltages provided by the window circuit. The window voltages establish frequency, and may be adjusted based on the input and output voltages. The timing circuit provides timing indications during the buck-boost mode to ensure that the second and fourth switching states have approximately the same duration to provide symmetry of the ramp signal.

摘要： A voltage regulator including a converter and a modulator. The converter includes a switching circuit coupled to an inductor for converting an input voltage to an output voltage. The modulator controls the switching circuit in a buck mode of operation, a boost mode of operation, and an intermediate buck-boost mode of operation. During the buck-boost mode of operation, the modulator controls the switching circuit during each switching cycle to sequentially switch between three different switching states, including a first switching state that applies the input voltage across the inductor, a second switching state that applies a difference between the input and output voltages across the inductor, and a third switching state that applies the output voltage across the inductor. The modulator is controlled based on voltage applied across or current flowing through the inductor to regulate the output voltage to a target level.
