help
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.
DO NOT DISABLE UNLESS YOU KNOW WHAT YOU ARE DOING.

help
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:
- TI-TLV62569/TLV62569P: 14
