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.
Why does the…
Part Number: UC2854B I changed the Vloop paramer, Iloop parameter,Vrms parameter, Iac parameter, Frequency parameter, Isense parameter, But PF was still the same when I added to half load which was 0.95
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

Part Number: UC2854B-EP Section 126.96.36.199 of datasheet (SGLS318A –NOVEMBER 2005–REVISED NOVEMBER 2015) discusses connecting a resistor (Rb1) from Vref to pin 6.
Page 5 of SLU177A (Revised December 2005) seems to indicate that this resistor …
