There is this post “TPS84620 used as LED driver” Although I do not need to drive LED’s the question is essentially the same.
The target devices I have picked are the: TPN78000/78020/78060 These are all voltage adjustable regulators.
There is a resistor to ground that sets the voltage output. I have voltage feedback that I could apply to the part. Some parts will allow this, some will not.
If I can do this please let me know what the Vref is so I can make sure I design the circuit correctly. Note that it would be great if the voltage was less than 1.0 Volts, but I can pretty much deal with anything.
Does anybody have any ideas that my help.
I am using a linear devices and a TIP35 is just disipating way to much power and I really do not have a way to get rid of the excess heat, and I would really like to use a switching device.
