UCC28950 / variability data of the ramp signal

K.Yaita

Hi Team,

The datasheet shows the range of ramp-signal is from 0.8V to 2.8V.



Do you have variability data of the ramp signal?
I would like to know the variability value like 2.8V±xx%.

Best Regards,
Yaita

    Hello Yaita-san

    I don't think that we have this data. The feedback loop will compensate for variations in the ramp - you mentioned ±2% as an example. The important thing is that the range of the error amplifier output (COMP) is greater than the range of the ramp signal.

    I hope this answers your question, if not then please reply.

    Regards
