Hello
I need schematic for TOSHIBA: PA750L auto adapter (18 volt 4 pin) its not on
the websight.
Not ONE person at Toshiba's "expert" tech support knew what a schematic,
pin out, DC-DC converter even was !!!
Well at least they were VERY nice and spoke understandable English, Anyway
after more calls up the ladder, as expected "authorized service eye's only"
I was **given** 10 Toshiba 18 volt auto adapters and want to bring them down
to 16VDC for an older single +VCC IBM barrel plug IBM ThinkPad Laptop (10 of
them).
Im assuming a Zener diode or LM*** 3 amp regulator IC off the secondary
filter caps, just wondering since the Toshiba's pack had 4 pins current
sensing feedback is involved complicating things.
Yes I can go hunt for 10 of the proper OEM, or replacement power supplies
on Ebay but that's not an option at $ $25-65 .ea
