Is it possible for LTC3331 IC to charge the battery prior to providing a regulated output?
No, keeping Vout regulated is prioritized over charging the battery. So the battery will not be charged until Vout is in regulation.
That said, if Vout is bouncing in and out of regulation, it is possible that the battery could charge eventually. Current will only be delivered in the times that Vout is regulated.
Thanks for the reply Zack
