The PSM features high resolution ADCs that accurately monitor voltage and temperature.
By integration of the LTC2971 with quarter brick converters This high-resolution ADCs deliver voltage and temperature reporting typically within ±0.5% to 1.0% accuracy on the QB board, enable precise power budgeting. Current is measured precisely using inductor DCR sensing or external shunts.
Reliable measurements of voltage, current, and temperature give engineers deep insight into how this solution behavior under varying conditions, allowing them to safely push performance to its limits.
By programming EEPROM parameter limits and fine-tuning warning thresholds based on the telemetry, engineers can ensure the system consistently delivers maximum performance without triggering unnecessary faults. See Figure 2.
