不行, 这路电源必须保证使用调压AVS,这个在DM8168手册里面有要求的。

AVS is required for DM816x devices. Using a fixed supply voltage level will violate max/min operating conditions for some devices which may fall at the edges of the process corners. This will in turn lead to long term reliability issues and may cause complete device failure.
