Hi TI-team
My customer is using UC2854B-EP.
Normally, I think ENA operates at 2.35V or more.
However, there is a sample that operates with ENA around 1.9V.
VCC at this time is about 10.5V.
Vref also outputs 7.5V.
Why does the IC operate even when ENA is below the threshold ?
Under what conditions will it occur ?
Please tell me.
Best Regards,
Koji Hayashi
