switching power supply?

[zhi_yi]

hello, please tell me what is the advantages of using switching power supply??

is there any good tutorial / ebook that can guide me to learn how to design a switching mode power supply?

thank you for the reply

Here's a nice web page:

There are several very good SMPS design books. Search EDAboard for book suggestions.

The short answer is:
Switching regulators are more efficient than linear regulators.
~
One disadvantage is that the output noise is generally higher than the output noise of a linear regulator.

okay, thank you all

what make the smps generate more noise than the linear regulator??

thank you

your answer is word "switching".
because of fast switching it can make some noise such as electromagnetic noise.
it noise can effect on some systems.

They can also be made smaller/lighter for the equivalent current rating than a transformer based power supply.

To all the replies you got concerning more eficiency, less volume, consider also that if you use an offline SMPS ( one that is feeded from the power line ) you can obtain very easily a great line regulation. Is common to see SMPS with input voltage from 80 to 2240 ACV.

If noise is a problem, you can reduce it by filtering or addiing a post linear regulator.

In www.ti.com you can find more tutorials wich cover SMPS

I attach a file with links to many places full os info on the subjet. Hope this be usefull for you
