My goal is lowest system power (particularly in IDLE mode). Is there any advantage to going with the Freescale PF0100 PMIC over a 3rd party PMIC like the LTC3676 that simply provides power rails but is not as configurable? I am planning to use LPDDR2 and include a USB Host in the design, so I will need those voltages as well.
I am mainly interested in:
1) Does the simplicity of the LTC3676 translate in to less power loss in the PIMIC?
2) How does this decision affect the decision about whether to use the i.MX6SL built in PMU or not?
