Other Parts Discussed in Thread: LM25037
Customer is developing the push-pull with UCC2808x series, but they found when duty cycle is higher than 46%, the waveform will become abnormal. Thus, trying to adjust the RT/CT ratio to adjust the waveform.
The current test conditions are:
RT=2.5K Ohm
CT=1410 pF
Fsw=0.5 * 1.41/(RT*CT)=200KHz
Duty=46%
With above conditions, the waveform is ok. But we're worried if there is any risk with higher CT value or not because it is already over the SPEC definition.
In the other hand, is there new push-pull device you can suggest?
