PMIC SW3B voltage issue

Hi, In my iMX6D based design we have used the MMPF0100 to supply voltage and CPU/SOC core voltage and it's interface devices. Now I have provided SW3A supply to DDR3L but SW3B is not powering any interfaces (floating). When I measured voltage during power bring-up, I have observed that SW3A is providing me proper voltage (1.5V) but SW3B is giving me around 2V. Why is that so?

 

I have not yet programmed PMIC. I have just measured pre-programmed OTP voltage.

 

Could you please help me to solve this issue?

 

Thanks

Mrudang.
