Tool/software:
Hello,
My question is in regards to the Cout requirements of the PPHV pin. The typical Cout is 47uF with a max of 100uF. The PPHV pin for my design goes directly to a subsequent buck converter stage. The buck itself has around 20uF of Cin. How do I combine these capacitances?
Since they are the same node, am I supposed to use a combined figure? Or are they considered separate because my PPHV Cout caps are close to the TPS25730 and buck Cin caps are very closely placed to the buck?
What if the two circuits are placed very close to each other?
Thanks,
Wilson
