I bought an LM2596 board from amazon, and I want to control it's output voltage from an arduino. My plan so far is to replace the trimpot with a network of 2 resistors and a AD5206. One resistor will be in parallel and one in series with the AD5206 to clamp the output voltage between 3V and 11.4V:
The only problem is, from the data sheet for the LM2596:
When using the adjustable version, special care must be taken as to the location of the feedback resistors and the associated wiring. Physically locate both resistors near the IC, and route the wiring away from the inductor, especially an open core type of inductor.
If I build this circuit on a breadboard PCB (with solder) and then wire it to the trimpot terminals on the board, will it be too noisy? The switching frequency is 150kHz.
