Hi team
1. Could you share the measurement condition of Theta_JA for TPS54427DDA? Customer is wondering 42.1℃/W can be used at their condition, that is the 4 layer board.
2. How do they estimate the value of VFBTH at the 5~50 degree C, though VFBTH is specified at -40 to 85C at the datasheet?
Regards,
Noriyuki Takahashi
