Hi,
We are using TPS54162QPWPRQ1 in one of our application and wants to confirm whether HTOL test done by TI covers the below mission profile or not?
Mission profile :
Maximum Power dissipation: 450mW
Junction temperature rise above ECU internal ambient temp: 11 °C
|
ECU External ambient temperature. |
ECU internal ambient Temperature |
Duration of ECU exposure to the given temperature [h] |

Tj would be 24 degree high with respect to ECU External ambient temperature.
