TPS6590376 SMPS7 and SMPS9 configuration

Other Parts Discussed in Thread: AM5728

Hi,


We have designed AM5728 based design in one of our project. Recommended PMIC for AM5728 is TPS6590376ZWST which we have used in our design.

We are not able to configure the SMPS7 & SMPS9 in our design by writing the SMPSx CTRl & SMPSx Volage registers. When we configure any value in the SMPSx CTRL & SMPSx Voltage registers we are getting 3.3V only. Kindly help to configure the SMPS7 & SMPS9 regulators.

Suggest which registers we need to configure apart from SMPSx CTRL & SMPSx Voltage registers as suggested in Reference manual.
