Part Number: 66AK2H06
Other Parts Discussed in Thread: UCD74120, UCD7242
Hi,
I have a customer who is designing 66AK2H06 custom board.
He is using EVM2K as a reference (see below power block).
Q1) There are two UCD74120 ICs used for CVDD (ARM and DSP AVS power supplies).
I guess this is only because one UCD74120 is not enough to supply CVDD.
Correct?
Q2) UCD7242 has two channels and each one is used for CVDDD0V95(= CVDD1 for DSP) and CVDDA0V95(=CVDD1T for ARM), respectively.
I understood each channel can supply up to 10A based on UCD7242 datasheet.

Why two channels are needed to provide CVDD1 and CVDD1T?
Using only one channel for both power rails may cause an issue?
Thanks and regards,
Koichiro Tashiro
