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.
