Hi support team,
I want to use only Vo2 and Vo3 of TPS65105.
Can I use Vo2 and Vo3 without Vo1?
If possible, is it okay if the red frame parts of the reference circuit shown below are not mounted?
As a result of not mounting, the pins in the blue frame become floating.
Please let me know the correct pin treatment.
VCOMIN: GND connection.
BASE: VIN connection.
FB4: VIN connection.
ENR: GND connection.
VCOM: Floating.
SW, FB1, SUP: Please let me know the treatment.
In my opinion, it is impossible because Vo1 is input to the SUP pin and used as an energy source for Vo2 and Vo3.
・ Use Vo1, Vo2, Vo3
・ Do not use VCOM or Vo4
I think it is possible to use it.
In that case, are the following pin treatment correct?
VCOMIN: GND connection.
VCOM: Floating.
ENR: GND connection.
BASE: VIN connection.
FB4: VIN connection.
