Hello,
I use TPS65910A31A1 for AM3352, and VDD2 of TPS65910A31A1 and CVDD_CORE of AM3352 are connected.
I have a question for the capacitance between two devices.
In datasheet of TPS65910A31A1, Filter capacitor Co(VDD2) is from 4uF to 12uF.
And in datasheet of AM3352, the decoupling capacitor of CVDD_CORE is 10.04uF.
So, I connect 10uF as the output capacitor of VDD2 and 10.08uF as the decoupling capacitor of CVDD_CORE.
The sum of two capacitances is 20.08uF.
Now, the combined capacity exceeds Filter capacitor Co(VDD2) of TPS65910A31A1.
Is this correct?
Should I set the combined capacity into Filter capacitor Co(VDD2) of TPS65910A31A1?
Best Regards.
Nomoto
