Anyone know of a supplier who has stock of Fairchild Semiconductors
KA1H0265R in the 100KHz 4 pin TO-220 package? The KA5H0265R is meant to
be equivalent but appears to only be available in a TO-220 5 pin
package?

According to Fairchild,

http://www.fairchildsemi.com/pf/KA/KA1H0265R.html

While the KA5H0265R is given as a replacement, and comes in a 4 pin
and 5 pin TO-220 as well as an 8 pin DIP, the availability is "not
recommended" whatever that means.

With the inherent problems this brings, long lead times and massive MOQ
from anyone who admits to having heard of it.

I've found that Mouser have stock of one of the KA5H0265R devices, but
the datasheet gives the type as a five pin device, I may order some if
Mouser will ship to the UK and experiment with the fifth pin.

I would assume that to mean that they have some, but
don't guarantee that they'll get more or be able to
get more.

_Make_ more?

Looking into it a little further, at:

http://www.fairchildsemi.com/pf/KA/KA5H0265RC.html

it looks like they're still making and selling them, but they're not
recommended for new designs.

Their "FPS" (Fairchild Power Switch) lineup is here:

http://www.fairchildsemi.com/whats_new/green_fps.html

and it looks like they've got some fairly kick-ass stuff available for
new designs.

Yes, you're right, make more would be correct.
What the 7734 was I thinking? )

But of course, why recommend the less expensive older
components when they have newer more expensive ones in
the making. )

Now, now, Bill... Be fair.

Fairchild's making a lot of the legacy stuff that nobody else seems to
want to screw with, and charging less for it than most. That is, last
time I looked.

Plus, IMO they're good guys trying to come back to life and I sure
hope they make it since I have fond memories of doing 400MHz logic in
the '70's with their 100K ECL, and I'd like to see them shine again.

Oh no, didn't I grin big enough again. 8O)
How's that, do you see it this time. )

These new parts *are* low cost ($0.92), and may actually lower the total cost of a design. But their appeal to me is in wasting as little as 300mW at "standby" power levels, while delivering 300mW to the load, e.g. see FSDH0265RN. You get say 5.0V at 60mA from the AC line, while consuming only 0.6W, which is 5kW-hr/year. Cool. And save$3/yr in
electricity. Now that's an honest low cost design!

Thanks,
- Win

Thinking about it, there might not be anything wrong with get. They may
have abandoned fabrication, and outsourced the manufacture. The fab
company might want a standard setup fee and if the marketers decide that
the costs outweigh the projected sales, and they might lose money on it,
then they might not submit a request for quote from the fab company.

Well, if you want to take it out of the realm of conjecture and
determine for sure whether you've actually gotten ahold of the straw
you're grasping at, you might want to contact them and try to find out
why that part is moribund and whether or not they really do make it.
Otherwise, a search for winged frogs might be apropos.
