Hello all,
The TI datasheet page 2 http://www.ti.com/lit/ds/symlink/lm117hvqml.pdf , Figure 3 shows the LM117HVGW-QML 16-Pin CFP pin connections.
It also has a statement that says "For the CFP device to function properly, the “Output ” and“Output/Sense ” pins must be connected on the users printed circuit board."
The schematic diagram on page 3 only shows 3 pins connected.
What is the 4th pin (Output/Sense) and why do the outputs have to be connected on the users printed circuit board for the CFP device to function properly?
