34063 output -6.5V [Copy link]

34063 does not output -6.5V, there is no voltage at all. Is it because the parameters are not correct?

Before using a chip model, you should at least find the datasheet and read it several times (note: several times, not just once).

Even if you follow the typical circuit described in the datasheet, you can't just pick a few components and put them together.

At least look at the component values in a typical circuit.

Changing C1 to 1N is a perfect solution

"Changing C1 to 1N is a perfect solution"

It's far from perfect.

The capacitor is changed to 1000p?

Just change the capacitor to 1000p?

Yes, you can just remove it.

Haha, what is perfect?
