Hi TI expert,

Hardware platformL TDA4+ TPS65941213RWERQ1+LP876411B4RQKRQ1, Reference PDN: DRA829_TDA4VM_Leo2.0_Hera2.0_PDN-1A_v0.16; 

Question : BUCK and LDO are not output ,all BUCK and LDO have 15 pulses after power up .All The power timing is normal .

values of all registers :

I have a question now. 0x40 register is 0x08, VCCA is + 3% accuracy. Is the value of 0x40 the default of tps6594?

Now the voltage value of VCCA is 3.4V. Is it because of this problem.
