Hi Everyone,
This is something I have somewhat been struggling with and it's the point where I need to ask for some help. I know the original DCDC converter I wanted to use wont work so you can ignore it in the following diagram (its the one labelled output adapter).
This diagram should just paint a picture of the inside of a single battery pack that I plan on using.
I'm looking for a non-isolated DCDC converter that can boost the battery voltage in the range of 5.4 - 8.4V to the system voltage of 12V.
The catch is that I want to parallel this DCDC converter with others of the same type.
So I would want to parallel three or five of these to share the load and provide more power to help the system run for longer.
At max I would pull 3 Amps peak from a single battery pack for a short period, which will decrease with each additional pack.
I know Vicor modules, etc have a trim function, is there anything similar that TI offers that I can possibly use for this solution or a well explained method to change the feedback loop to accomplish this?
Thanks in advance for any help, it would really really be appreciated!
EDIT: In the diagram I forgot to remove the arrow that says feedback to trim output voltage. I was planning on doing something like this although I highly doubt it will work
