Re: [CAD_CAM_EDM_DRO] Re: Help wanted

Hello Ballendo
thanks for halping me.
ucn5804 i am covernig it with proper heat sink but when i put it on heat
sink it will not mounted in pc board . it will be wired for connection.
i have TIP120 power transister but it is not working. i put it that one leg
is earth one output and thired is input direct. total circuit voltage is
12v. 5804 pin 9 11 14,16 is out put and 10,15 is 12 volts. if u hav esome
idea or circuit for 3055 or tip120 for 5408 please send me.
Thanks all.
