  3. hi all colleagues this is a new and absolutely free to post, upload and download service manual and repair tips in most electronic filels : http://ib.forum77.com/index.php?mforum=technical& best regards
  4. hi Naw_S i have this one .. hope it'll help u solve ur problem best regards E70F.rar
  5. hi cm thank u for ur response .. i've already do many searches online and came across this System General company and already got an account .. they also offer a free samples but not for this IC ( pin to pin). they do have a very good collection of power managements ICs and some of them already used in some atx power supplies. best regards
  6. hi cm well , i don't really have a data sheet but have a circuit diagram contains this IC which is working in an ATX computer power supply and has both the PWM controller and supervisory section merged into this IC .. the problem is i can't find it .. any equivalent or replacement or even one supplier ??? i'll upload the circuit i have and hope u can find any replacement or supplier .. please post if u do find any best regards
  7. hi hotwaterwizard thanks for all the help u try to do for me .. unfortunatly this is not my IC .. mine is DR-B2003 it's a pwm + supervisory .. atx power supply IC .. the problem it's unavailable here so i need a replacement or equivalent for this IC or where from i can get it? thanks alot Best Regards
  8. hi hotwaterwizard thanks for all the help u try to do for me .. unfortunatly this is not my IC .. mine is DR-B2003 it's a pwm + supervisory .. atx power supply IC .. the problem it's unavailable here so i need a replacement or equivalent for this IC or where from i can get it? thanks alot :) Best Regards
  9. hi all yet again i have another atx power supply using the same chip to control it and the common thing is the number 2003 .. i have this chip with that printed on it in two rows also : 2003 BAZ42860403E that means the part number is 2003 but what does this mean? any idea please ? Best Regards
  10. hi all please guys help to find replacement for this IC .. what replacement or equivalent i can use? where i can get this IC from on line store? what part number should i use to order ? please help if u can thanks in advance Best regards
  11. hi all colleagues i've got the pinouts of this IC and now i need a replacement or equivalent for this one or where on line can i buy this one thanks in advance Regards
  12. hi hotwaterwizard thanks again for all the help u try to give , but all the the schematics here are based on the 494 chip or equivalents pin to pin which is different from my chip on this power supply .. here's another more information i've got from the board of the power supply and hope it'll help more : i got some more information that may help idenfifying this IC this atx power supply model is : LC-B350ATX with the following outputs : +3.3V@28A +5V@35A +12V@16A -12V@0.8A -5V@0.3A +5V SB@2A also i found this printed on the components side of the power supply unit : Y-B200ATX Ver: 3.1 the pinouts of the IC that i could figuer out were : Pin 1= Vcc Pin2 connected through 3.5K resistor to the green wire for PS-ON pin7= output 1 to the switching transistors Pin8 = output 2 to the switching transistors Pin9 = PG ( power Good) pin 12= GND hope this will help more in identifying this PWM controle chip thanks in advance Best Regards
  13. hi hotwaterwizard thanks alot for ur reply trying to help me :) i've already had those schematics and more , the problem is that most of the schematic i have found online using the 494 chip or equivalent , but the one i have here do have different IC with strange number and different pin-outs .. i mean not pin to pin equivalent to the 494 chip .. this is my problem . if i can get more infor about it , it'd be easy to make any modifications using available parts . thanks alot Best Regards
  14. hi all i have a computer power supply (ATX) that have a faulty PWM IC this IC has a strange part number printed on it in two rows : 2003 BAZ37430407H i need a data sheet or pin-out for this IC with 16 pin DIP and if there's any other equivalent of the well known kinds it'd be highly appreciated . please help if u do have any info and where can i find it online to buy thanks in advance Best Regards
