Hi Team,
cusotmer uses TPA3144 for the new project.
We use the TPA3144 EVM PVDD 7.5V to get the GVDD 6.91Vrms.
however, customer's PCB board PVDD 7.7V, only get the GVDD 5.3V. so the gain value is wrong for the original setting.
Why the LDO output has much different GVDD value? Please provide your comment and usggestions.
Could you please provide the relation between PVDD and GVDD curve?
BR,
SHH
