PWM genration by SG3525

[Powerelec_sci]

hello,
i want to generate PWM with SG3525 frequency 25Khz and use both output of IC output A and output B. Output A PWM duty cycle variation 10% to 40% and Output B PWM duty cycle variation 40% to 90%. suggest me RT and CT valules or schematic.

SG3525 has a datasheet that gives some tables or curves for RT and CT . did you see them ?

Best wishes
