Other Parts Discussed in Thread: TPS54429,
Hello teams
We want to check the behavior of TPS54429/TPS54425 with 12vin/5vout setting on TINA TI.
But it's output ramp up only til 4V on our design.
And Both Vout level is decreasing gradually until around 3.5V.
As you can see in our schematic,
it's behavior would happen with noload situation.
Why their output do not reach to 5V even if feedback resistances are set to 5Vout?
Our designs reffered example design of TI.
It's url is bellow.
