Is the N5768 power supply capable of sinking current? I would like to use it in an application where there is another power source (perhaps another N5768) set to a fixed voltage, a load, and then the N5768 on the low side, regulating the current coming out of the load. Is that possible to do? If not, is there another power supply capable of doing that?
It would make it very clear if you had provided a sketch of your setup.. If i understand your application correctly you are trying to sink a significant amount of current, unfortunately this power supply does not have this capability. The N576x series does have a very light sinking capability that the main operation is for discharging the internal output capacitance of power supply during transient response performance.
