Abstract: A current detection system includes an inductor and a detection circuit coupled across the inductor. The inductor is configured to receive an input signal that includes an input current and generate a voltage across the inductor. The current detection circuit includes a sensing network and a transconductance amplifier. The sensing network includes a capacitor and is configured to monitor a voltage across the inductor. The transconductance amplifier is configured to receive a differential voltage indicative of a voltage drop across the capacitor and output a differential output current proportional to the differential voltage.

Abstract: A voltage converter includes a high side power transistor coupled to an input voltage node and a low side power transistor coupled to the high side power transistor at a switch node. The switch node is configured to be coupled to an inductor. A slope detector circuit is configured to receive a signal indicative of a current through the inductor. The inductor current is a triangular waveform comprising a ramp-up phase and a ramp-down phase. The slope detector circuit also is configured to generate an output signal encoding when the inductor current is ramping up and when the inductor current is ramping down.

Abstract: A circuit and method for providing improved load transient response in a DC-DC converter. A DCM modulator is incorporated into the converter controller to generate a DCM enable signal for the driver circuits for the converter. During normal operation, the DCM enable signal will remain in a first state and the driver circuits will operate in a continuous conduction mode. However, upon a load transient, the DCM enable signal will change to a second state and the driver circuits will operate in a discontinuous conduction mode.

IPC: H02M7/537
Abstract: A power controller comprises a control loop configured to control timing of pulsed signals that activate phases of a coupled inductor voltage regulator based on current demand of a load circuit and comprises a transient detection circuit configured to determine a projected current through a compensation inductor of the coupled inductor voltage regulator based on a state of the phases and operating parameters of the coupled inductor voltage regulator. The transient detection circuit is configured to detect a transient in the current demand of the load circuit based on a variability in phase-to-phase overlap of the pulsed signals. Responsive to detecting the transient, the transient detection circuit is configured to apply a correction to the control loop that alters the timing of the pulsed signals based on the projected current through the compensation inductor.

Abstract: At least one example describes mechanisms to improve performance of a multiphase voltage regulator. In at least one example, an integrated circuit is provided which includes control circuitry coupled to a first power stage and a second power stage. The first power stage and a second power stage are coupled to an output power supply rail, wherein the control circuitry generates a first pulse width modulated signal for the first power stage and a second pulse width modulated signal for the second power stage. In at least one example, the control circuitry aligns rise and fall times of the first pulse width modulated signal and the second pulse width modulated signal based on an undershoot condition being detected on the output power supply rail.

Abstract: Aspects of the disclosure provide for a circuit, in some examples, including a storage element, a co-processor, and a telemetry sequencer coupled to the storage element and the co-processor. The telemetry sequencer is configured to implement a digital state machine to receive configuration information indicating a type of telemetry data for generation, retrieve operations and operands, where the operations and the operands define a sequential series of actions for execution to generate the telemetry data, drive the co-processor with the operations and the operands by passing some of the operations and some of the operands to the co-processor for processing by the co-processor, receive, from the co-processor, and store an intermediate output of the series of actions as the telemetry data in a first format, and receive, from the co-processor, and store a final output of the series of actions as the telemetry data in a second format.
