Part Number: UCC28C43-EP

I chose to model the ucc28c43-ep's oscillator with a PSIM model of the ucc3842 (see attached file).

I sought out information about the current source value and the two treshold values for the ucc28c43-ep but I could not find the exact information (see attached file).

Could you tell me those exact values for the ucc28c43-ep or give me the related documents which would allow me to calculate those values.

In addition I would like to receive information about the circuit's architecture of each function of the ucc28c43-ep in order to do an easy model.

I look forward to your response.

Thanks&Regards

Hi Eric,

The applications engineer supporting this device is on business travel returning on Monday. There might be a delay until then in getting answers to your questions.

Thanks

Hey Eric,

What values are you specifically looking for?

If its not in our datasheet its unlikely I will be able to provide it.

Thanks,

Daniel

Hi Daniel

I'm looking for where I can find in ucc28c43-ep's data sheet or related documents, the value to take for the current source (5.1814mA in the attached file, it's the

value for the ucc3842) and what values to take for the two comparator's threshold values (0.6667V; 0.418V in the attached file, are the values for the ucc3842).

Il look forward to your response.

Thanks&Regards

Hey Eric,

If you are talking about the discharge current of the oscillator this is specified in the datasheet.

We do not however provide the threshold values for the oscillator for this device.

Thanks,

Daniel
