Part Number: UC2854B-EP Other Parts Discussed in Thread: UC2854B , , UC2845 Hi,
I am currently designing a PFC with a boost topology.
In my design, it is preferable to use an external op amp to do the voltage loop function,
The output of this external op…
Part Number: UC2854B-EP Other Parts Discussed in Thread: UCC2818-EP , Hi,
The UC2854B-EP has the same functional bloc as UCC2818-EP, better current amplier bandwidth, low gain dispersion of multiplier but requiere more supply current and it is more expensive…
Part Number: UC2854B-EP Other Parts Discussed in Thread: UC2854B , Regarding a 400Hz 115Vac input PFC module for military avionics application:
In doing higher temperature testing (baseplate > 70 deg C), the THD begins to increase from ~3% to ~10% (seems…
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-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
