TL494: Frequency fluctuation Issue

Sadanori Kato

Part Number: TL494

Hi,

The duty should change, but the frequency may change when configuring the closed loop with LT494.
So, I will share the schematic and screenshot via a private message if you can accept my friendship request.
Could you please tell me the root cause and workaround ?

Best regards,
Kato
