Part Number: UC3853 Tool/software: Hello Everyone, here when i simulating the circuit i'm facing the error like this.
Here i attached the images
step:1
step:2
here i clicked " Stop the simulation and run the new one ."
step:3
finally…
Part Number: UC3853 Hi!
I have a small query in PFC compensation implementation.
I understand that we have to consider the worst case conditions (low-line and full load) while designing any loop compensation.
But why is that the low-line of PFC…
Other Parts Discussed in Thread: UC3853 I need a SPICE model for UC3853 (High Power Factor Preregulator).
I need it to run a simulation in LTSpice. I already checked the TI.com site and google but no success.
That would help Me a lot in My simulations…

Most PFC controllers will work with a DC input. Most of TI's PFC controllers have been tested with an input frequency of 47 to 63 Hz. All of the PFC designs that I have done are in the 47 to 63 Hz range. I do know of some customers using the UCC3817/8…
Hello Amit,
Thank you for your suggestions. So I studied my hardware. I am designing a DC/DC converter (SEPIC) with 100kHz switching frequency. We are operating 4 converters in parallel/interleaved for current sharing. so I will be needing 4 PWM signels…
Hello Reinhard,
Unfortunately the EVM is no longer available. The EVM schematic is shown in the UCC3750 datasheet page 6. Attached is a PDF showing a bill of materials. UCC3750 EVM slua103.pdf
That waveform is 20 Hz triangle centered on ground. 20…
