Other Parts Discussed in Thread: CSD87350Q5D, , TPS650861
Hi
We are considering TPS6508640 to be used along with Xilinx ZU7EV.
Ordinally, 0.85V rail, such as VCCINIT etc, requiring large current consumption.
(Our estimation is over 30A or so)
So, we will use BUCK2 controller with CSD87350Q5D for this rails.
I have questions for power sequences.
1. TPS6508640 will operate with the default value listed in Table 3-1 of the datasheet.
Is it possible to change these default values?
2. If the answer to question 1 is “NO”,
is it possible to change the output voltage after starting up with default value?
3. Figure 6-4 and Figure 6-5 of the datasheet show power up/off sequences.
Are these sequences just fixed? Or changeable by user?
BestRegards
