mas

are you shure? :o what i say bro? this project powered ac. i want use smps (dc). i say will not work. because there are no sine wave for negative supply.. and i say ILC7660 usable for this.. okay? red marked area for negative supply..

Look please...

this circuit working with old transformers. designed for transformers supply (sine wave) alternative voltage. will not work on dc voltage. because you can not converte positive dc to negative whit passive components for opamp supply..

i have a question, can i use ILC7660 for negative opamp supply? i think use smps. transformers is very big,heavy,expensive,old vs.. thx..

hi all; i maked this psu first version. it is worked very good but damaged. after i think make a new and more profesional. i look your updates and make a new pcb. i complete all but dont complete pcb routing. i want one side pcb. proteus autorouter draving 2 side. i dont want 2 side. i want only 1 side. maaybe need change component placing. can you complete this? i attached all files.. im using proteus 7.7 sp2. thanks. regards.. 0-30v_stablized_new_pcb.rar
