Near to the Nec FIP display in the Newbrain computer
there is a little
circuit with a componet with 10 pins where you can read:
27
CD-1867N
TDK
JAPAN
Somebody know what is this component? I think it is used to control
voltage
supplied to de display.
If it's a small circuit board, it's probably a DC-DC converter (or a
DC-AC inverter, if the display needs AC). Many Ethernet cards used to
use a TDK CE2054 DC-DC converter to produce isolated 9V DC from 5V DC in
I've got big pile of surplus ones, and the data sheet *used* to be on line,
but I can't find the copy I downloaded and now it's no longer on their web
site.
