Using DVFS with external DC-DC power supply

Hi all,

 

In i.MX6 processor family, for DVFS to work successfully , is it neccessary that Internal Digital LDOs are for powering on ARM , SoC & PU ?

Is there a method to make DVFS work when the digital LDOs are used in bypass mode ?

 

 

My concern here is if we use LDOs , drop across the LDOs itself will result in power consumption .

If we can control the DC-DC converer present externally for DVFS , this voltage drop across LDO can be eliminated.

 

Please share your thoughts.

 

Regards,

Suresha.N.S.
