Hi everyone, can someone help me?, I am using SG3525 for my Push Pull inverter design but each time I design it I get voltage not up to 220v, maybe 201v even if I had Feedback to My circut. Can anyone tell me the Adjustment I to do to get a voltage of 250v without Feedback. Thanks
 

Feedback can only reduce the output voltage by decreasing the duty cycle. Looks like wrong transformer design or excessive ouput stage voltage drop.
 

Connect sg3525 pin 1 to pin16 .
and pin 2 to ground.
It will disable feed back loop and make duty of output pwm to its maximum value.
