Hi there!
I'm interested in using TPS61178 to boost my PSU voltage.
One feature we'd like to implement is the TPS61178 VOUT tracking its VIN.
For example,
- PSU VIN = 11V, VOUT = 15V
- PSU VIN = 12V, VOUT = 16V
- PSU VIN = 15V, VOUT = 19V
Is the TPS61178 capable of doing this if we have an external circuit connected to the FB pin?
We were thinking of using an a voltage divider on the PSU VIN and feed that into an voltage follower op amp circuit, then the output of that op amp would feed the FB pin of TPS61178.
Does TI have any experience with this kind of requirement? Any tips on implementation?
Thanks,
JCKK
