I want to add a Variable voltage/frequency option to my power supply.
I read that a Multivibrater can do this. But I cant find a datasheet that explains the pins. I have a CD74HC221EE4 , SN74LV4046ANE4 (cmos logic w/voc) , HCF4098BEY also i have a UC252AN its a pulse width mod?.
Which would be the best for a Variable voltage/frequency power supply.
