Part Number: TIDA-01505

Tool/software:

Hi team,

My customer follows the design of TIDA-01505. But the VOUT is high to 13.5V under low temp but normal under room temp and high temp..

Below is the issue conclusion.

Support needs:

1. Do you have some suggestion for next debug to locate the root cause?

2. Could you support one board for this EERD to my customer to test the VOUT under low temp?

BR,

Jasper
