TPS56121: TPS56121 as a constant current source

Part Number: TPS56121

Tool/software:

Hi, I would like to use the TPS56121 converter as an adjustable constant current source for a nonlinear load (diode). The target parameters are: output voltage of a maximum of 8 volts, maximum current of 12 Ampere.

For this I would use current sense resistor with a current sense amplifier plus an additional amplifier for setting the desired current and feed the signal back to the FB pin.

Is there an application note for this or a similar converter? If not, what do I have to pay attention to so that, for example, no unwanted oscillations occur or other stability issues?

Thank you in advance

Dimitrij
