Q: TPS61040 Vin to Device and Inductor by 12504

I have a customer who is asking if he can connect the inductor directly to his battery (8V to 17V) instead of Vin to the device in his product which is 3.3V. The output voltage to the 6 LEDs in his system is 19.2V.

Yes.  The TPS6104x family supports "split input rail" configuration.
