I'm guessing so. Am wondering if the 1.67 amp 24
vdc
regulated wall warts from BGMicro are sufficient to
power an 8" floppy drive (NEC FD1165-A). Needs 24 vdc
@ 18 watts. Would love to devise a circuit to get the
5 vdc (@ 5 watts) off the same brick, but that may be
asking too much ;).
24v 18W is .75 A, well within the stated specs.
5v 5W is 1A, so a liniar regulator would overload the wart, besides
needing to dissipate 19W.
A switching regulator should have no problem doing the 24v to 5v 1A
conversion.

examples.
