- These are my general thoughts: -
- - Easiest - power management IC (PMIC)
- - Smallest footprint - PMIC usually
- - Cheapest - usually PMIC (for a certain minimum performance level)
- - Highest performance - PMIC will outshine all others
- - Best reliability - PMIC
- - Best stability - PMIC
- - Quickest reaction time to load changes - PMIC
- - Quickest reaction time to incoming voltage changes - PMIC
- - Least start-up overshoot - PMIC (especially boost converters)
- And now the bad things: -
- - Unreliability - microcontroller
- - Instability - microcontroller
- - Noisiest - microcontroller
- - Poor reaction time to load changes - microcontroller
- Poor reaction time to input voltage changes - microcontroller

- > _which one is better in the long run and also how to mitigate its drawbacks?_
- Use the better one - if the better one still has drawbacks then extra circuitry may be required to overcome limitations but, without a specific application/job in mind this cannot be answered.
