Part Number: UC2854B-EP 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.
…
Part Number: UC2854B-EP Hello, Team,
My customer is using UC2854BMDWREP. They plan to change SS capacitor from 0.01uF to 22pF. Could you please let me know the equation for SS calculation?
Best Regards, Satoshi Yone
