Dynamic voltage and frequency scaling (DVFS) is a power management technique that allows dynamically reducing power consumption of a CPU by dynamically scaling down supply voltage and CPU frequency. Because the internal DCDC of the i.MX RT1170 cannot cover the needed maximum current requirement at the junction temperature of 125 °C, the DVFS technique can be used to reduce current drain for compatibility with the internal DCDC. Lowering the processor frequency dynamically can help reduce the chip input current demand and ensure that the chip can continue to work at the junction temperature of 125 °C.
