I want a circuit for Switching DC-DC coverter. Input 24 VDC and output
12 VDC 10 amps. Please give me some ideas or circuits.

Why wouldn't you just use a solid state voltage regulator IC. They areatul said:I want a circuit for Switching DC-DC coverter. Input 24 VDC and output

Why wouldn't you just use a solid state voltage regulator IC. They are
ready to go right off the shelf. Something like an NTE-933 will
regulate up to 5amps and if you didn't want to parallel two of these
you should be able to boost the current using power transistors of the
proper size. If you were going to do that you might start with an
NTE-1954 (a 1 amp regulator and cheaper) as your reference regulator
and boost that with power transistors. The whole point is to avoid the
complexity and losses of a DC to DC conversion process. Keep it
simple.

a cinder overnight! (;-)

Getting rid of 120W without driving a linear regulator into thermal
overload protection is hard work and requires a big heatsink with a low
thermal resistance to ambient, which usually means fan-blown.
It isn't the earth that turns into a cinder overnight, but the project
costs.
John said:Why? It's dull being 68 and a bit. I'd rather be my shoe-size (British
size, preferably, but I'll settle for Continental).
Indeed. I abjectly apologise for writing 240 W in error.
You haven't understood a bit, have you? What do you think is the
significance of that odd word 'magenta' in this context? Followed by a
ridiculously exaggerated comment about global warming?
In message said:Haven't a clue - a google search on "magenta" and another on
"magenta+global+warming" didn't help either. Do tell ...
John said:Magenta is the complementary colour of green - as near to an 'opposite'
as you can get in the context.
I think we should form an International Magenta Party, to combat the
worst excesses of the green movement. You know, opposing the restoration
of a landfill refuse site because it would displace the seagulls [1].
fundamentalist muslims provide endless examples - one of the stronger
arguments against the existence of god is his failure to spend a few
lightning bolts on the likes of Ian Paisley and Osama bin Laden.

is their tendency to over-state and over-simplify their case. I've
pretty much lost patience with the Dutch branch of Greenpeace -
listening to them is like being exposed to a non-stop TV commercial, a
continuous stream of emotionally loaded non sequiteurs. Worse, my wife
still gives them money ...
Once the rent-a-crowd fanatics latch onto a cause, no matter how
worthy, principle goes out the window. Fundamentalist Christians and
fundamentalist muslims provide endless examples - one of the stronger
arguments against the existence of god is his failure to spend a few
lightning bolts on the likes of Ian Paisley and Osama bin Laden.
