Hello people.

I am interested in learning SMPS design and I'd like to know if is there any
good book about them?

Yes, indeed, there are a number, but I'm sure you don't
want to purchase a few dozen books! How about telling
us more about your switching-supply interests?

I am mainly a hobbyst but I have some "technical" training in electronics, and I
am interested in learning about some basic SMPS design.

I'd like a book for the completely newbie in SMPS design (like me).

What book would you recommend to a completely newbie?

Thanks.

There are a number of books on the subject; Google should still give
some decent references.
However, i have not seen any of them that give sufficently detailed
info so one can *actually* design and build a switching supply using
real-world parts that one can buy.
There is always a "magic gap" of missing info.

Hello people.

I am interested in learning SMPS design and I'd like to know if is there
any
good book about them?

depends what you want to know. Here's a few:

1) Power Electronics: Converters, Applications & Design - Mohan, Undeland &
Robbins, Wiley, ISBN 0-471-50537-4

- a good all-round power electronics book. Almost enough info to figure out
how to make something, but not quite. same goes 4 theory & analysis

2) Switch Mode Power Supply Handbook, K. Billings, McGraw Hill, ISBN
0-07-005330-8

- excellent. a bit light on analytical stuff, but reams of info on how to
make a real SMPS. Good info on magnetics, too.

3) Switching Power Supply Design, A.Pressman, McGraw Hill, ISBN 0-07052236-7

- quite practical, fairly empirical as far as theory goes, but a lot of
practical advice on how to make something actually work. Lots of real
waveforms too.

4) switch-mode power supplies, Whittington (I have this scanned).

- quite practical, no analysis only results stated.

5) dc-dc switching converters, Dan Mitchell, McGraw-Hill.

- All about state-space averaging, and modelling/control. not for the faint
hearted.

6) resonant power converters, M. Kazimierczuk etal, Wiley, ISBN
0-471-04706-6

- more theory than you can shake a plethora of sticks at. heavy going, but
provides in-depth analysis of a variety of resonant inverters & rectifiers.
If you dont want to play with resonant converters, avoid this book

In addition, I would avoid anything published by TAB books (they are
invariably rubbish, cobbled together from apps notes), likewise J.D. Lenk's
book. I havent read it, but I heard the one by Marty Brown was fairly good.

Some of the best literature is app notes - Unitrode in particular. Get hold
of unitrode design seminar "books" - many can be downloaded from www.ti.com

I'd say Abraham Pressman's book comes pretty darned close... he's using
ancient old controller ICs that are still around (albeit under different
names now, sometimes) and transformer cores that you can get through, e.g.,
Amidon.

"A Boy's First SMPS Tutorial Kit" would be nice (something where you get a
bunch of parts to play with on a breadboard for various common SMPS
configurations and a text that explains everything), but I imagine the sales
volume would never justify the cost...

The National 'Simple Switchers' are purposely designed to make getting a
working circuit trivial (at the expense of transient response and
efficiency); those are a good place to start as well if you just want to
concentrate on one area of SMPS design at a time, say, winding your own core
one day.

oh yeah, invariably right at the point you want to design the loop
compensation bits.....

Ed Bloom sells some of these for integrated magnetics - a complete kit, that
really does work.

i have seen more than a few of these screwed up, too - usually using the
wrong diodes/caps (can people not read?), and/or absolutely daft layout [how
hard can it be? 6 words: current flows in loops; minimise them]

You might try pouring over data sheets and app notes. If nothing
else, you'll find out what you *dont* know. Then you can look at
books' table of contents and see what looks good.

I'd recommend reading manufacturer's app notes, plus get and
read Pressman's book, "Switching Power Supply Design," because
he shows different configurations and you a good perspective.

Nope, you're labouring under a misconception. To me, (an) analogue is
something bearing an analogy, not a type of circuit. I don't write
"programmes" either. ;-)

That's "Wiley" as in coyote. Help me kill all my lame assed
teachers. It's their fault they didn't put "poring" in my vocab
lessons. I think the word sux now, so I'll just use "labouring"

Thanx anyway. Cud save me embarrassment later. OTOH, I know there
are people who would think "poring" was a misspelling.

Poring - Hunting for pores.

I once sold a kit where I had stuck all the 0.1uF bypass capacitors along
one 'string' on the schematic. One guy who built it dutifully stuck the
half-dozen or so caps all right next to each other exactly as shown on the
schematic, rather than spreading them around as intended.

Although it only had about three ICs on it, I suppose it was clearly not a
'beginner's' kit, since I hadn't bothered (in the instructions) to mention
discrepancies between physical layout and schematic representations!

LOL!

After reading "analog x analogue" as you and J. Thompson noted... I remembered
something that could be funny:

In Portuguese, "I am making a program" may mean:
- I am programming for PC/PIC/FPGA/whatever.
- I am making a movie, a small video clip.
- I am planning a trip, or a party for the weekend
- I am configuring an electronics device (TV/PC/cell phone/ham radio/whatever)
- and even "I am having sex" (!!) - I don't know the exact term in english, but
the rude way of calling here is 'whores' or for a less offensive, 'porn
actresses' - girls that do sex for a living.

LOL!

A good fix for that would be to give (at minimum) a "drawing" of the
foil layout.

I was in a similar position serveral months back. I found Fundamentals
of Power Electronics by Erickson/Maksimovic very useful.
I also bought Switching Power Supply Design by Pressman. It covers
alot of material, but is rather terse. Probably good if you already
have experience, but not as useful if you are just starting.
If you are really wanting to understand the theory, taking some time
to understand control theory helped me a lot. Search the edu sites for
lecture notes and problem sets.
Studying a wide variety of manufacturerer datasheets is needed as
well.
In the end I was able to successfully design a 1.8V and 3.3V switching
regulator which I have used with serveral projects.
It did take about two months of studying, simulating and
understanding, but I wanted to make sure I had good understanding in
case things did not work. It also helped to already have a strong math
and electronics background.

I am mainly a hobbyst but I have some "technical" training in electronics, and I
am interested in learning about some basic SMPS design.

I'd like a book for the completely newbie in SMPS design (like me).

As a few others said, read through data sheets and app notes from
various manufacturers, available on their websites: ti.com,
national.com, linear-tech.com, maxim-ic.com are the ones I can think
of offhand. Start with the Linear Technology app note AN25, named
"Switching Regulators for Poets."

What book would you recommend to a completely newbie?

I looked up Pressman's book (type Pressman for author, and switching
for title) in these two sites - it's not cheap but there are a few
used copies under $50:
http://www.bookfinder.com
http://used.addall.com

Since Win recommends it, you should go right out and buy it.

But if you want to be cheap, I think you can learn a lot from the
data sheets/app notes.

Thanks.

Pressman's recent edition is larger and of course much more expensive,
but used copies of the earlier edition are available for about $50, as
Ben says. In it he covers a wide range of converter topologies; it's
fine for a beginner. As for an advanced SMPS designer, even his new
expanded edition leaves one dissatisfied for more detail, although it
does command a place on the bookshelf. If Pressman's book is a guide
to appropriate technology; the manufacturer's datasheets and app notes
are guides to specific designs.

But this still leaves open the issue of magnetics design, an important
but somewhat advanced topic. Here I recommend E. C. Snelling's book on
the properties of Soft Ferrites, admittedly a more exotic fare. Those
deprived of a copy of Snelling's book will find excellent material deep
in the recesses of TI's website, where the old Unitrode lecture-series
material resides.

The phrase "MAGNETICS DESIGN HANDBOOK" is worth seeking out. I found
the writings of Lloyd H. Dixon especially useful, but there were other
good contributors to the series. There's altogether about 80MB of
material to download, unpack, and organize. Afterwhich the intense
studying can commence. :&gt

Good ideas. I will download some datasheets soon.
I am in Brazil so getting some books may be difficult.
