Part Number: UCC28064A Tool/software: Hi!
I am incredibly frustrated right now, simply due to the fact that your data sheets do NOT go into enough detail on how to select the appropriate inductor when the chosen operating mode for Boost PFC is Critical…
Part Number: UCC25661 Other Parts Discussed in Thread: UCC28064A Tool/software: How can I use the UCC256614 PFC ON/OFF function to control the UCC28064A? Can you provide a reference design?
Part Number: UCC25661 Other Parts Discussed in Thread: UCC28064A Tool/software: Can I use the TSET pin from the UCC256614 to the TSET pin of UCC28064A for disable the PFC when LLC enters into burst mode?
Part Number: UCC28064A Other Parts Discussed in Thread: TIDA-010015 , , UCC25640 Tool/software: The design of TIDA-010015 has a no load power of approximately 200mW, which does not meet the Level VII no-load loss requirement of within 150mW.

Part Number: UCC25661 Other Parts Discussed in Thread: UCC28064A Tool/software: I am considering a circuit using UCC256614 and UCC28064A. How should I best connect TSET (PFC ON/OFF) terminal to UCC28064A?
I am considering using the external disable…
Part Number: UCC28064A Tool/software: Hi E2E When I asked a question before, I was told that the maximum switching frequency was 300kHz, but when I checked the actual device, the maximum frequency was about 370kHz. What is the maximum frequency of the…
Part Number: UCC28064A Other Parts Discussed in Thread: UCC28064 Tool/software: Hello,
In the UCC28064 data sheet, a 4A fuse was chosen for the reference design. However, for the same example design, it states that during startup, the peak input current…
Part Number: UCC28064A Tool/software: Hi,
I have a 600W PFC, running from aircraft 400Hz, 115V AC - generating 400V DC for an LLC stage.
If I disable phase B (tying PHB high) , it works very nicely in single phase mode up, delivering up to about 270W…
Part Number: UCC28064A Tool/software: Hi team,
When VIN becomes high, the phases of A and B become misaligned.
From what point does the phase fail function start to function, and how does it correct it?
Part Number: UCC28064A Tool/software: Hi TI
Please tell me how to select the constant Rz(comp pin).
What effect does increasing Rz have?
Also, are there any recommended upper or lower limits for Rz?
As shown below, we have confirmed that the…
