CVDD电源可以将初始电压设为1.0V吗?



您好:

 我的DSP是6672,CVDD的电源芯片初始电压为1.1V时,上电后,DSP 发送VID给SMARTREFLEX会调整到1.0V; 如果我把电源芯片初始电压改为1.0v时,上电后SAMRTREFLEX会调整到0.9V,芯片也能正常运行且芯片发热要小很多(只装了散热器)。所以我想问问,初始电压按1.0V设计行不行?因为我想降低点功耗,批量使用有没问题?我看TI提供的参考电源方案都是把初始电压设计为1.1V的,且官方的HARDWARE DESIGN GUIDE提到“This power supply circuit must initialize to a level of 1.1 V and then adjust to the voltage requested by the SmartReflex circuit in the KeyStone I device.”

谢谢
