Part Number: TPS54240 Hello guys,
One of my customers is evaluating TPS54240 for their new products.
They use parts parameters which calculated by TPS54240 Webench.
Their Vin/Vo/Io conditions are the follows.
Vin = 33.2V(Min), 36.9V(Nom), 40.6V(Max)
…
Naveen,
You are probably operating in Low Voltage Dropout condition. See this document:
It applies to TPS54240-Q1 as well. Let us know if this addresses your issue.
