Hi TI team,
I am designing a power management circuit that has a normal mode where it provides external 5V, 3.3V, and 1.5V to my system.
I also have a low power mode in which the external power supplies are not available. In this case battery voltage that pass through BQ24075 needs to be buck-boosted by a PMIC to 5V, 3.3V, and 1.5V. Then I think I need some switches to switch these supplies to output instead of the external supplies to allow the system operate.
What are your suggested part numbers for PMIC and switch in this case. Thanks.
