I'm using a MC34063 to generate a negative supply for a vacuum fluorescent display, but it needs to be activated after the main 5v rail is up. I thought the easy way to do this is use the 5v supply to turn on the chip's Vcc connection, but THEN I thought, can I use it as the Vcc supply directly? There's no documentation I could see saying I can or can't. The main supply will be between about 7v and 12v.
What do you lot think?
