Tool/software:
Hi all,
My customer uses a TL594 to control CCCV charging using the following forward circuit.
【The conditions】
Vin:350V
Vout:4V
Fsw:50kHz
The output voltage increased by about 6~60 mV. However, the measurement results varied from day to day. The deviation was sometimes 6mV.
Does the output voltage fluctuate by about 6~60 mV?
In the past, have there been any cases of variation due to aging?
Is it caused by external noise?
I would appreciate any advice.
Best Regards,
Ryusuke
