+            ESP32P4 will switch the power supply to LDO before sleeping, and switch to DCDC after waking up.
+            These two processes take a long time and may bring some risks for some short duration
+            light sleep. (DCDC -> LDO: 2.5ms (max), LDO -> DCDC: 1.2 ms)
+            Enabling this option will make chip powered by DCDC during light sleep to reduce some power switch
+            risks, this will also increase the power consumption during the light sleep.

+            This value determines the voltage of the DCDC chip during sleep. The same parameter value may
+            correspond to different voltage values on different models of DCDC chips. Please update this
+            value according to the model of external DCDC selected in your hardware solution.
+
+            For the DCDC chip model recommended by ESP, the recommended configuration
+            valuesare listed below:
