PRODUCTION DATA
The telemetry sub-system in the controller core supports direct measurements of the following:
The ADC supports internal rolling window averaging with rolling windows up to 16 previous measurements for accurate measurements of these key system parameters. Each ADC conversion requires less than 500 μs, allowing each telemetry value to be updated within 2 ms.
The current sense telemetry senses the low-side FET current at the start and end of each low-side FET on time and averages the two measurements to monitor the average inductor current over-report current if the inductor current is non-linear during the low-side FET on time, such as when the inductor is operating above its saturation current.
