摘要： A variable frequency modulator including a compensation network, first and second pulse control networks and a linearity controller. The compensation network is configured to provide a compensation signal indicative of an output load condition. The first pulse control network is configured to initiate pulses on a pulse control signal and to adjust operating frequency based on changes of the compensation signal. The second pulse control network is configured to terminate the pulses on the pulse control signal based on a predetermined timing parameter. The linearity controller is configured to adjust timing of terminating the pulses based on a predetermined steady state operating frequency and an actual operating frequency to maintain modulator gain at a constant level.

摘要： A regulator system with dynamic droop including a regulator control network which is adapted to control regulation of an output voltage to a reference level, a DC droop network which provides a droop signal to modify the reference level based on output load according to a predetermined DC load line, and a dynamic droop network which adjusts the droop signal to delay recovery to the predetermined DC load line within an AC load line tolerance in response to a load transient. A transient reduction network may be included to reduce transient overshoot for load insertion or release depending upon duty cycle type. The dynamic droop network adjusts the droop signal to optimize utilization of an AC delay parameter while transitioning between an AC offset voltage allowance and the predetermined DC load line.

摘要： A modulator with balanced slope compensation including a control network, a slope compensation network, an offset network and an adjust network. The control network receives a feedback signal indicative of an output voltage and provides a loop control signal. The slope compensation network develops a slope compensation signal. The offset network determines a DC offset of the slope compensation signal. The adjust network combines the DC offset, the slope compensation signal and the loop control signal to provide a balanced slope compensated control signal. The DC offset may be determined as a peak of the slope compensation signal. The slope compensation signal may be developed based on the output voltage and a pulse control signal, in which the pulse control signal is developed using the balanced slope compensated control signal.

摘要： A predictive current feedback system for a switched mode regulator including a sample and hold network for sampling voltage across a lower switch of the regulator and for providing a hold signal indicative thereof, and a predictive current feedback network which adds an offset adjustment to the hold signal based on a duration of a pulse width of a pulse control signal developed by the regulator. Sampling may be done while the lower switch is on for providing a hold value indicative of inductor current while the pulse control signal is low. The offset adjustment may be added to the hold signal in response to a transient event when the pulse signal is high. The offset may be incremental values after each of incremental time periods after a nominal time period, or may be a time-varying value. Adjustment may be made while the pulse signal is low as well.

摘要： A dynamic voltage response network for a switching regulator with droop control providing a droop control signal includes a voltage identification setting network, a pass and hold system, and a reset network. The voltage identification setting network initiates a hold condition and adjusts an output voltage reference in response to a change in a voltage identification input. The pass and hold system passes the droop control signal during a pass condition and holds the droop control signal during the hold condition. The reset network resets the pass and hold system to the pass condition in response to a reset signal. The reset signal may be provided in response to a variety of conditions, such as load transients, proximity between the developed droop control signal and the held droop control signal, timeout after the output voltage reference is adjusted, among other reset conditions.
