My 18 volt power supply has 21 volts output, could this be the cause of my
problems? Pin 2 of the L2724 chip is at 21 V rather than 18v. I would think
that if that was a problem both L2724 chips should blow or at least not the
DEC one twice. {small sample set)
What voltage is the 18 volt power supply typically rated at?
---------------------------------------------------------------------------
The L2724 datasheet says supply voltage 28v maximum.
My power supply from Meade does not have any voltage regulation.
It outputs 21v no load, 20.5v @ 0.12amp, 18.3v @1.14amp.
This voltage should not cause any problems.
