i try to get stable +12/-12v by using double mc34063, one is step down converter and other is inverter .. i have checked every thing on a breadbord for both configuration and i got +12 and -12v seperately. but when i designed both of configurtion on a board and tested, at the negative converter circuit , becoming overheating at coil 8L1) and the capacitor (c6) is exploded and the mc34063 (U6) is burned... i checked many things and checked all connection, it looks there is no problem. my opinion what the both circuit is in interaction, but how i could not understand... i am not so experted on electronic circuits.. could any body please help me and give advices?? thanks in advance.. .
