Other Parts Discussed in Thread: UCC21520
Tool/software:
Hello, I'm Cheol-ha kang.
I am a hardware engineer based in South Korea, specializing in the development of converters for the automotive industry.
First, before I ask about the UCC21551, let me briefly describe our topology as follows:
1. Topology : PSFB Converter
2. Swtiching Frequency : 96kHz
3. Dead Time : 150ns
4. Circuit
Now for my main question: Will there be any problem if I design the INA/INB input filter like the attached circuit, which is different from the design recommendation in the datasheet below?
we've implemented an RC filter with 1.6kΩ and 10pF, which results in a cut-off frequency of about 10MHz.
My question is, are we allowed to use values other than those specified in the datasheet's recommendation? I would like an answer on whether it is acceptable to apply our current filter values, even though they deviate from the recommendation, and if this will cause any problems.
I look forward to your prompt response.
thank you.
