Web30 mrt. 2024 · Since DVFS optimizes both the frequency and the voltage, it is one of the only techniques that is highly effective on both dynamic and static power. Dynamic voltage scaling is a subset of DVFS that dynamically scales down the voltage (only) based on the performance requirements. Adaptive voltage and frequency scaling is an extension of … WebPower Domain overview, the GD32L233 series device has three power domains, including the VDD / VDDA domain, 1.1V domain, and backup domain. The VDD / VDDA domain is directly powered by the power supply. The LDO is embedded in the VDD / VDDA domain to power the 1.1V domain. There is a power switch in the backup domain, and when the …
Web4 sep. 2024 · The worst case is when your battery is full at 8.2V. The voltage across your LDO is : 8.2V - 5V = 3.2V. The current through the LDO is 100mA as we defined. The power that the LDO has to dissipate into heat is : V * I : 3.2V * 100mA = 0.32W. Now it's time to check if the LDO is able to dissipate that.
