ATX Power Supply modification Symmetric 2X30V DC DC Converter Circuit sg3525

Symmetric SMPS auto amp supply (DC / DC converter) sg3525 PWM control integrated circuit built on the output MOSFETs are driven in two stp60n06 the power transformer transformer ei33 is most commonly used in computer power supplies

EI33 transformer handing out you do not find in the market again you can use the wrap. Prime 12v mosfet section 2 × 5 rounds (4 pcs 0.6mm wire parallel). Secondary + – 30v output section 2 × 12 tour (2 pcs 0.6mm wire parallel)

Output for bridge rectifier UF5407, BY399 diode or transistor type is stronger than I used diodes pc power supply 12v output of the diode bridge I’m using 3 of the money for the MOSFETs as irfz44, used irfp3710

ATX Supply modification

For two-channel stereo amp circuit TDA7294, TDA7293, LM3886 integrated amp in the pictures below of the two available power supply circuit and the PC seems to state coffers placed

CAR AUDIO AUDIO power amplifiers. Converter has been made ​​according to the scheme of the Internet and it is not by me. I will describe only the transformer because the rest needs no description. Transformer won the ATX power supply model LC-ATX that I got from a friend for the rest of the proverbial beer possessed of surplus. So the cost of small, only two evenings and desire.
