I'm struggling to increase duty cycle in the controller. I'm using SG3525 on control PCB. As can be seen below, R12,R22 and C12 components are selected for 58kHz frequency.
However, I can't get duty cycle more than 45%. Typical duty cycle is given 47% in datasheet. Does the max. duty cycle limited by frequency?

Datasheet only guarantee 45 % duty cycle. You should not expect more.
