Hello,
We have identified TPS63070 for one of our project .
This will be used as Buck boost converter to power the board from battery input. Presently we are looking for 3.6V battery . We may use 6V battery if required.
Below are the 2 cases of application.

When we tried to do simulation in TI web bench . This is simulating only up to 1A and above 1A it is giving error.
I doubt whether any duty cycle limitation is causing this problem ?
As per datasheet switch can be used for 2 A current rating in both boost and buck mode and there is seamless transfer will happen from boost to buck or buck to boost.
Please clarify whether this chip will work for above input and output requirement.
Thanks
