This error amplifier configuration conventionally has a resistor from the inverting input to common, and a resistor from the multiplier output to a negative…
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…

In doing higher temperature testing (baseplate > 70 deg C), the THD begins to increase from ~3% to ~10% (seems…
Part Number: UC2854B Other Parts Discussed in Thread: UC2854 Hi Team,
Good day.
Could you help us provide the HBM and ESD Rating of UC2854BDWTR? Thank you in advance for the help.

Part Number: UC2854B Hi, I want to design PFC using UC2854B under the following conditions. Input : AC85V-265V, DC125V(-10%, +15%) Output : DC390V 200W Efficiency : 90% Switching frequency : 65kHz
In this case, can UC2854B be used with both of AC and DC…
Part Number: UC2854B Other Parts Discussed in Thread: UCC2818 What is the ABS max voltage allowed on the CT pin (for cases where there is an external sync pulse injection)
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…
