Part Number:TPS2490
Hi
My customer has question.
■ Specification
Vin = 12 V
Iout = 40 A
The FET was damaged while the customer was evaluating the TPS 2490.
The waveform at that time is this.
While the customer slowly lowered the input voltage, near the UVLO
Customer believe that the TPS2490 has exceeded the SoA of the FET as a result of repeating starting ⇔ stopping, and the FET was damaged.
Is this correct?
Are there other possible factors?
Best Regard
T Kishi
