How to design a power supply unit



How do I design a power supply unit with:


Input: 230 Vac
Output: 5 Vdc, 500 mA

Use Switching Regulator for my design.



Answer



Perhaps you could make the question a little more specific.


If you are looking for a general tool or guide to switch mode power supply design, there are several on the net, as well as free online design tools on the web sites of manufacturers such as:




Many of these tools go as far as providing a schematic, a bill of materials, performance parametrics and even design simulation, all for free.


If on the other hand, you would like someone to design one for you, this might not be the best place for that.

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
