PF3001 regulators

[riteshpatel]

Hi,

I am using PF3001 PMIC in my design to power iMX6UL processor.

PF3001 is available with pre-programmed OTP configuration to support iMX6UL. Programming option is 7 (i.MX 6UL with DDR3L) and part # is MC32PF3001A7EP. As PF3001 Datasheet page # 3.

As per power startup sequence shown for programming option A7 on PF3001 datasheet page #29. Sequences of VLDO2 and 3 are OFF.

So can we leave floating VLDO2IN, VLDO2 & VLDO3 pins?? Here floating means leaving floating without decoupling capacitors.

Thanks,

Ritesh.

Hi Luis,

Thanks for quick response.

I think this patch is related PF300 PMIC.  I need patch for PF30001 PMIC.

Can you please share what changes should I have to change in order to use PF300 u-boot driver for PF30001 PMIC.

Thank you igor for your quick response.

I am using PF3001 in my design. Suggested AN4717 sch guideline is for

PF0100. So can i use this recommendations for PF3001 too.??

[igorpadykov]

yes, this is the same family of pmics using similar technology.

Hi Igor,

Thank you for your extended support.

We are using PF3001 PMIC in our project.

Is it possible to use PF3000 PMIC drivers on PM3001 PMIC?

If yes, What changes are required?
