Part Number: UCC28064A Hi TI Team,
My customer design a boost converter using the UCC28064A.
The input needs to meet both DC 127V and AC 85~265V.
There is a start-up delay Issue when using DC input, but not with AC input.
Can you explain the reason…
Part Number: UCC28064A Tool/software: Hi team,
Adding a snubber circuit will change the load that transitions between operating modes (burst, single, dual).
Is it possible to use a snubber circuit?
If so, are there any concerns about using a snubber…
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 Tool/software: Hello,
Please refer to the UCC28064A data sheet for the TSET resistor calculation, which controls the converter MOSFET on-time. This calculation is supposed to use the maximum expected inductor value, which would…
Part Number: UCC28064A Tool/software: My input VAC is 85V - 265V, which is a standard universal AC input.
The maximum voltage rating for the ZCD pins is 4V, which is pretty low. The calculations in the data sheet state to choose a turns ratio such that…
Part Number: UCC28064A Tool/software: Hi team,
When VINAC becomes distorted, the pulses from GDA and GDB stop.
What kind of protection circuit is in place?
Yellow:VINAC、Green:IAC、Pin:GDA、Blue:GDB
Best regards,
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.
