In one of my design I using TPS54561DPRT with "UVLO" protection. I using standard connection type like is recommended in datasheet (SLVSBO1G...page 18.).
It works fine in temperature range from -40°C to 50°C.
As soon as the chip temperature is higher than 50°C (±5°C), the "UVLO" function is not working.
It is used in design where required temperature range is from -40°C to 100°C.
Through measurements, I found that the current source located on the EN pin inside the chip supplies 2mA and more, which is much more than the mentioned 1.7uA.
I think "I1" doesn't work correctly.
