Other Parts Discussed in Thread: TL494

Hi,all

Please let me ask you a question about TL494 fold-back current characteristics.

Fold-back current characteristics are written on Figure25. of Application Report "Designing Switching Voltage Regulators With the TL494",however Vo is same voltage in both Ik case and Isc case ?

At actual measured result , Vout drop proportionally as Iout up .

What does stable Vout of fold-back current characteristics mean ?

 

I am looking forward to your reply.

Best regards.
