Other Parts Discussed in Thread: UC2843,
Dear Team,
We find the UCC2895 PSFB's Vds(CH2 green) noise will affect UC2843 Buck's Pin4 triangle waveform(CH1 yellow), so the Buck duty will be abnormal
As you can see waveforms, when the Vds is not switching the triangle waveforms don't have noise.
Do you have ideas how to solve the PSFB Vds noise, or how to improve the Buck's noise immunity?
Buck:500~1200Vdc==>225Vdc
PSFB:225Vdc==>48Vdc
Waveform:
