I have seen that in sg3525 based power inverter , the overload protection module incorporates two opamps, why is this so? i mean we simple monitor the current and compare it with a reference , using one opamp and connect the output of opamp to the pin 10 of sg3525. but many schematics contains 2 opamps in cascade , why?
1. sg3525 in ON semi and Motorola library. 2. LMD18200 in NSC(National SemiConductor) library. in schematic page press P.P(shortcut)>>choose>>find>>sg3525* or LMD18200* >>search.

Hi greetings may be this schematic be helpful HAVENT tried it warm regards andrew lebon
For us to help you, we would need you to upload a schematic. That would help us find out where the problem lies.
i have the following schematic for 50hz 12v to 220v dc. i have foud it from internet but not yet tested it. The problem is that how i can adjust pin no.2 the duty cycle by giving feed back from output 220 to obtain pwm? does it only require modification on the pin 2 or whole circuit needs to be changed? 58210 [ATTACH=CONFI
For 800W output its ok an half-bridge with 2xIRFP460 mos-fet's,or STE40NK90ZD super mosfets. Don't need synchronous rectification for output.Its ok an dual 30A/200V fast recovery diode. For PMW IC its better an sg3525 IC than TL494. For schematic check diyaudio forum.You find lots of schematics there.
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? thanks
hi guys does anybody know anything about switching type audio amplifier. actually it modulates the input signal into PWM signal and take it to the output. the actual question is what tips or tricks are involved and do you know any good schematic? do you know any circuit that uses sg3525 for it?
I don't have a paper, but I went to the ON Semi webiste and in their datasheet you can find the actual oscillator schematic: See Fig. 7. So let's try to derive our formula and see which one is correct. From that figure, we can see that the cap is charged by a constant current, given by the c
Hi Please refere to the data sheet of the IC, This will help you get the basic circuit for the allication. WHat voltage level are you looking at? Please send spec so that a schematic can be posted. Please alos send power level. Thanks Hari
Hello 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
