The question sounds confused, because SG3525 is a pwm control circuit. What you probably mean is how to connect a buck switcher to the IC. SG3525 has two outputs with < 50 % duty cycle, so you would need to combine both outputs to drive the buck switch. sg3524 provides a simpler way to get > 50 % output duty cycle, so it's usually preferred.

I dont know exactly what is the min freq of sg3524. but less than 1Hz also it'll support. for ur req sg3524 (SG1524 or SG2524) is one of the best solution. ref circuit: .
- pg no. 5
In other hand u can use 4017 with 555.

Actually there is '-' ,'+', and comp terminals for sg3524 pwm controller.. i m designing isolated converter for our application. i need to isolate the voltage sensing which is given to '-' terminal of the error amplifier.. how to acheive it..? any idea or example circuit..?
Usually i used to go with tl431 and optocoupler at the feedback (...)

I want to ask, if I have a 0-12 transformer in place of a 12-0-12 transformer, can I use the same sg3524 based pwm inverter circuit by just using four Z44 mosfets in place of two by making the transformer lying between H-bridge?
The linked image is for showing the idea. Original design of mine that has

Are you referring to the Microsemi sg3524 pwm controller? If so I would start by reading the data sheet.
As far as understanding how a Microsemi sg3524 based inverter circuit works, I would start by reading up on inverter circuits and their operation. Just search for Inverter circuit design (...)

Hi, this can be a problem, if you look into the forum i post some inverters circute diagram using sg3524 pwm ic it work fine with modified sine output,and to control the inverter on when ever their is power supply failure normaly the shut down pin is used for the control.

The sg3524 has a very good advantage over monolithic cd4047 cus the output can be automatically adjust to normal a.c voltage when there is variation in load.
The auto adjust is possible when there is feedback signal to the pin 1 of the ic, the circuit i have worked, but does not have a feedback.
