Switch Mode Power Supply SMPS circuit mentioned this in my article, but wanted a 12 volt 40 amp circuit can be overlooked for SMPS circuits in the mail, this circuit has led me to write a separate article :)
Quite a powerful SMPS 40 amp LM3524 is built around integrated instead SG3524 or UC3524 can be used to integrate the same manufacturer only different circuit output voltage of 13.8 volts, but the output voltage standard 12 volts can set the overcurrent limit heat protection used to have output power transformer a little different :)
