I test Figure 6. Current Loop Gain (TdB (f)) and Figure 7. Current Loop Phase (qc (f)) in SLUA479A
The Schematic(page 2) in SLUA479A
I actually tested it and have some question…
Part Number: UCC28070 Hello.
I am planning to use two UCC28070EVM to make a 4-phase interleaved PFC but even though I read UCC28070 datasheet I still don't get how to synchronize two modules together.
It will be very helpful if you answer the questions…

Can you find the Winding Information of the transformer applied to UCC28070EVM? I found out about the transformer (7508111120). But I did not know Winding Information.
Dear Nikhil Gupta,
Thank you reply ！ I need a complete model,can you share me a SIMPLIS model? I have a SIMPLIS simulator.This is my email :291769742@qq.com.

Hi Chuck, thanks for your reply.
Here are some answers to the points you raise:
a. X-axis is time elapsed, in 10nS units. Y-axis is gate ON time, in 10nS units. As your MOSFET Gate Voltage traces show, the voltage is a ON/OFF voltage 0v to voltage…

Part Number: UCC28070 Tool/software: Hello, I am working on 500W PFC design using the UCC28070EVM. I recalculated component values using the Set-up Tool SLUC114 Rev 2.0 and applied these changes to the EVM. The boost inductors are MnZn (example Wurth…
Part Number: UCC28070 Tool/software: Hi
I noticed a confusing discrepancy in the placement of the current sense transformer in two different designs using the UCC28070 PFC controller. In the 1200W version, the dot on the transformer is located at the…
