Do you have a link to the datasheets because i cant see it in those i have. dont you think i can make it as a buck converterHI ELTOCK
you need a step down and a voltage inverting converters
the two diagrams are in the datasheet of MC34063A
you may need an adjustment to your required voltages
I am all new in electronics, sorry.Do you have a link to the datasheets because i cant see it in those i have. dont you think i can make it as a buck converter
i am all new in electronic. the thing i cant figure out is det circuit that comes after the mc34063a where the output to +5v and -5v is
Thats why i am asking, because i am New, and Thats why i need specific diagram over the outputIf you are that new to electronics, this is a really really bad first project for several reasons:
If you are trying to construct a power supply for experiments, I suggest you start with two 9V batteries and a pair of linear regulators producing ±5 VDC supplies. This circuit will work just fine on a breadboard. Get your feet wet before trying to swim the English Channel. You need to learn to crawl and walk before trying to run a marathon.
- You should not build this design as a one-off breadboard.
- It should be fabricated on a PCB (Printed Circuit Board).
- The knowledge required to select the proper components exceeds your current knowledge level by several orders of magnitude.
- The diagram above is for the buck converter ONLY!
- You need a separate design for the negative supply.
You really really need to learn how to find and download datasheets.
For the positive regulator you google: "LM317 datasheet"
The following link is the first non-advertising hit:

For the negative regulator you google: "LM337 datasheet"
and this is the top hit

Get the idea?
I get it all. But it is important that it is a mc34063a says My teacher, All I need is det +/- output diagra.Thats why i am asking, because i am New, and Thats why i need specific diagram over the output
You didn't say there was a teacher involved, and you didn't post in Homework Help. His motivation for introducing you to a Switch Mode Power Supply (SMPS) at your level of knowledge is beyond comprehension. You should find another teacher before you hurt or injure yourself. Your teacher must be beyond incompetent. Good luck BTW.I get it all. But it is important that it is a mc34063a says My teacher, All I need is det +/- output diagra.
You can try using TPS54060 chip from Texas Instruments. Check the datasheet below, in Page 40 (Figure 64) you will find an application diagram where you can use the chip to split the rails and obtain positive and negative output voltages.Hi. i need a diagram over an smps, the input set to 9V from an 9V battery to +5V/500mA and -5V/200mA on the output, and i use an mc34063a?
That looks like a cool part. Have you used it?You can try using TPS54060 chip from Texas Instruments. Check the datasheet below, in Page 40 (Figure 64) you will find an application diagram where you can use the chip to split the rails and obtain positive and negative output voltages.

I have used similar one, at least I am familiar with the application, so if you have any question your welcome to ask.You can try using TPS54060 chip from Texas Instruments.

I would like to use a mosI get it all. But it is important that it is a mc34063a says My teacher, All I need is det +/- output diagra.
Single question? Is it possible to Make buck-boost converter and an ext mosfet, with + and - on the outside?You didn't say there was a teacher involved, and you didn't post in Homework Help.

Sure. How did you fabricate the transformer?I have used similar one, at least I am familiar with the application, so if you have any question your welcome to ask.
