Other Parts Discussed in Thread: TDA4VM
Dear Expert,
Currently we are trying to use the PDN-0B PMIC(TPS65941212 + TPS65941111) module for TDA4VM(Soc) power supply, The BUCK1,BUCK2 & BUCK3 output for TDA4VM AVS module power supply as show below(Follow TI recommended tpical design):
As far as i know,The VDD_CPU_AVS powers the A72s, C7x / MMA, and the MSMC , While we switch on C71x DSP core( runs up to around 50%) we measured the VDD_CPU_AVS current from the PMIC BUCK inductors（L4 or L5 or L6） output as below (single power rail current):
It seems the scope shot current is anbornal ,single power rail peak current up to 5A, I would like to know what is the expected current required for VDD_CPU_AVS current when TDA4 runs up on normal condition(as A72s, C7x / MMA core switched on on normal operation load).
Many Thanks
