UCC256304: UCC256304 was evaluated, Duty cycle was not 50%.

Dear Benjamin Lough,

Thank you very much for reply.

I confirm customer schematic and waveform, but
May I ask a question?

Would you teach the reason for checking the VFB voltage waveform?

Best regard.
Bob Lee.

Hi Bob,

If the FB signal is not stable, then the internal VTH and VTL can change in the middle of a switching cycle which would look like unequal pulse widths.

Best Regards,

Ben Lough
