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: 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.

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.
