Part Number: UCC28070A Other Parts Discussed in Thread: UCC28070 , Dear Sir, I have designed the 1 KW Interleaved Boost PFC Converter using UCC28070. I am attaching the schematic of the design. I am facing the problem while running it. I am not been able…
Part Number: UCC28070A Other Parts Discussed in Thread: UCC28070 Is it possible to run the Interleave PFC Converter to run only on Single Phase by just disconnecting the inductor of 2 phase?
Part Number: UCC28070A Other Parts Discussed in Thread: UCC28070 , Hello, The problem I am facing is that driver outputs of UCC28070 are simultaneously switching during both half-waves. Usually first half wave only Q1 should switching and second half wave…
Part Number: UCC28070A Other Parts Discussed in Thread: UCC28070 What will happen if I apply DC voltage instead of AC to the line input ?
Will it lead to any damage to any part of PFC circuit ?
What is the range of DC voltage which can be applied to the…
Part Number: UCC28070A Other Parts Discussed in Thread: UCC28070 Hello,
I am designing a 3800W PFC whose particularity is to be able to provide 3 different output voltages, 420VDC, 470VDC, 530VDC for specific needs on the equipment to be powered downstream…
Part Number: UCC28070A Other Parts Discussed in Thread: UCC28070 Dear Sir,
I am attaching the schematic and UCC28070 design file. Kindly please verify my calcula Mathcad - UCC28070 Design Tool .pdf tions for 1 KW design. Please let me know, if any changes…
Part Number: UCC28070A Hello,
UCC28070A's programmable peak current limit function (PKLMT) uses a signal voltage at CSA/CSB pins. Therefore, an output current when the peak current limit occurs may differ depending on the input voltage since a peak current…
Hello,
You are correct that you can reprogram the peak current. I forgot the device has this feature.
I am not sure that you are using equation 63 correctly from the application note. Could you double check your calculation.

We request that you forward this to the manufacturer TI…
Part Number: UCC28070A Other Parts Discussed in Thread: UCC28070 Hello,
UCC28070A's data sheet has Equation (18) to select R IMO value. But if a signal voltage at CSA and CSB pins has DC offset, does it have an effect on the Equation (18)? I'm wondering…
