AM5728: 上电要求

Part Number: AM5728
Other Parts Discussed in Thread: TPS659037,

我原来有设计一块SOC(FPGA+ARM)板卡,给SOC供电(FPGA+ARM),选了官方推荐的供电模块,基本上把所有的电压都包含了,但是电路板回来后供电没起来,因为是BGA的封装,也不方便找原因,耗时很长且整个板卡作废了,因此我对一个模块供所有的电有点心有余悸。

现在我要给AM5728配置电源,我看到了官方demo板采用TPS659037供电,我想,能否用很多DC/DC芯片来代替它?是否可以?AM5728的上电顺序是否一定要满足?如果不满足要求的话,即使每路电都供了,AM5728不能起来,对吗?(SOC是能起来)
