soft-start circuit of UC2845A

Other Parts Discussed in Thread: UC2845A, UCC38C42

We have questions about UC2845A.

We try to design the soft-start circuit by using this application note p.14 figure.12 about UC2845A.

This application note is published in web page of UC2845A.

Please tell us the formula to set the value of external parts(resistor, capacitor and so on) in soft-start circuit.

Is there a limit to soft-start time?

Best regards,

Takahiro Nishizawa
