I have made car amplifier 1x100W 4ohm.The dc/dc converter is made with sg3525 PWM, two buz11 mosfets,torodial ferite trafo.The Amplifier is consist of one pair tranzistors tip35c,tip36c.
I HAVE MADE IT AND IT SOUND PERFECT.Now i need schematic for making dcprotection for speaker.
Here is the schematic and picture

hi guys, i need some help here
i need to build a buck converter from 12v to 9.6v to supply to a motor.
i must generate pwm using sg3525. i google oledi.
but seems cant find much sg3525 used in buck converter. mostly are for motor control. do any1 have similiar schematic for this?

I don't have a complete schematic, but since you want low-weight and high efficiency, SMPS would be a good choice.
Here's an here for some ideas including a posted circuit:

I don't have a schematic, but the feedback circuit of your example can basically work. The feedback amplifier should probably have a PI rather than a pure I characteristic for faster response.

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.

Here is the schematic. The configuration is exactly same with the schematic given with the model files. I have changed components to meet my design settings.
Here Vout is required to be at least 24 (Output voltage divider is much higher in the schematic for test purpose only)

what is the purpose of resistors and capacitors at pin 1 of sg3525.how it works.i've used this type of feedback but except resistors and capacitors at pin 1.but output voltages is not 5amperes load,output voltage drops by 2.5V and at 8 amperes,it drops by this a normal case or I can make it better by proper fee
