I'm looking into Linear Technology's LTC3566 PMIC for an upcoming portable design. Its a really nice PMIC with a buck-boost regulator on-board. Here is the typical application:
The reason I want to use this part is cause it allows me to save board space by not having to include a DC/DC regulator. In my application, I would power my entire circuit of Vout1 and skip the use of Vout altogether.
The one part I'm not clear about is this section here in the pin descriptions:
I have two concerns:
- It says the majority of the load should be powered by Vout - In my application i would power my entire application from Vout1. Is this a concern?
- The chip is smart enough to partition input power between Vout and the battery. Do I still get that functionality by using Vout1?
