Abstract: In described examples, a controller includes a converter. The converter generates a first signal responsive to an input signal. A summing block is coupled to the converter. The summing block receives the first signal and generates a second signal. A limiter is coupled to the summing block and generates a third signal responsive to the second signal and a code signal. A logic block generates a target signal responsive to the third signal. The third signal transitions to an intermediate level at a first slew rate and the third signal transitions from the intermediate level to the target signal at a second slew rate.

Abstract: An example non-transitory machine-readable storage medium includes instructions that, when executed, configure processor circuitry to at least: determine a first delay corresponding to an amount of time for a first pulse to reach first phase circuitry; determine a second delay corresponding to an amount of time for a second pulse to reach second phase circuitry; determine a third delay corresponding to an amount of time for a third pulse to reach third phase circuitry, wherein one or more of the first phase circuitry, the second phase circuitry, and the third phase circuitry are located a non-uniform distance from the processor circuitry; and transmit, based on the delays, the pulses to the respective phase circuitry such that a first time period between the first pulse and the second pulse is equal to a second time period between the second pulse and the third pulse.

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.

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: Provided herein are various enhancements for voltage regulators and associated control schemes that provide power to fast transient load circuitry. In one example, a power controller includes a transient detection circuit configured to monitor a change in timing among pulse signals associated with voltage conversion phases supplying current to a load circuit. The transient detection circuit is configured to identify a transient event condition corresponding to a change in current demand of the load circuit, and responsively output an indication of the transient event condition.

Abstract: In some examples, a circuit includes a state machine. The state machine is configured to operate in a first state in which the state machine gates a pulse width modulation (PWM) signal provided for control of a power converter according to a first signal provided by a voltage control loop. The state machine is configured to operate in a second state in which the state machine gates the PWM signal according to a second signal provided by a current limit comparator. The state machine is configured to transition from the first state to the second state responsive to the second signal being asserted after the first signal is asserted in a switching cycle of the power converter. The state machine is configured to transition from the current state to the first state responsive to the first signal being asserted after the second signal in a switching cycle of the power converter.
